all right, so it&#x27;s not a couple of calculations here, so we&#x27;re looking at the number more, um, metal Adam in the following comparison. So the 1st 1 looking at 10.0 grams of calcium versus can point zero grams of calcium chloride. So the 10 gram sample of calcium has a larger number of moles of calcium metal than the 10 gram sample of calcium chloride. And why is that? Because this is pure calcium and calcium. Chloride has two bowls of chlorine for each mole of, um, calcium in each molecule. Now, for the second comparison, we&#x27;re looking at 5.0 grams of sodium chloride versus um, 5.0 grams of sodium fluoride. So the 5.0 grams of sodium fluoride should have, uh, the larger number of moles of sodium metal, then does the five grams of sodium chloride. And why is this because flooring is or has a lower molar mass than chlorine does, So five grams of sodium chloride should contain mawr atoms of sodium than does five grams of sodium chloride for the same mass of each sample, and third, we&#x27;re looking at 2.0 grams of iron oxide f e o versus 2.0 grams of iron sulfide F E s. So sulphur is a heavier Adam, then oxygen is so that makes, um, iron oxide a lighter compound on a molar mass basis. Then Sodi, uh, iron sulfide. So that means we&#x27;re gonna have a greater number of moles of iron oxide that iron sulfide for the same mass of each.

Okay, So which has more Adam&#x27;s 10 grams of calcium or 10 grams of carbon? It should be whichever Adamis smaller and in this case, carbon is smaller. So logically carbon should have more Adams if we&#x27;re holding the same, um, amount of mass for each, But let&#x27;s verify that. So if we have 10 grams turned in 0.0 grams of carbon on and we calculate its number of Adam&#x27;s, we need to multiply by its more mouths. So one mole of carbon Look on the period table, Um, has 12 0.11 well, or grams from all and then using all my God rose number for our next compression factor to get Adam&#x27;s. Um, when you plug that in your calculator, you get five point no one times 10 to the 23rd atoms of carbon, where anything is actually in problem process for our 10 grams of calcium. So I&#x27;m gonna take one mole of calcium, and I&#x27;m actually gonna wait for more mass so I can just finish writing this line of text. Okay, so now I&#x27;m gonna look up. Calcium. Calcium is in the yellow column here to the 3rd 1 down, right there. It&#x27;s 40.78 So 40.78 grams, no doubt in my calculator, and I get 1.5 zero times 10 to the 23rd. Adams of Calcium says. You can see here 5.1 is bigger than 1.5 And that is do because the only thing that&#x27;s different in these, um calculations are the boulder masses. So carbon had the smaller molar mass. That means for the same amount of mass, it will have more Adams.

So we have to convert 10 bowls of carbon and 10 most of calcium into the numbers of Adam&#x27;s. So start with the carbon. So just not supplied by six point on T Time Center is where 1/3 Gadahn&#x27;s, I think. What is explaining to time. 10 to 24th and it owns carbon. Same thing for 10 years of calcium. Same number since we&#x27;re multiplying the same numbers here. So therefore, the answer to the question is they have equal number of Adam&#x27;s equal, and each Adam are. Each one has has 10. Most of carbon has this many. Adams 10 mostly calcium is suspended. And 10. Let me just write this out, really.

Ethan Fuhrman · Answer

Okay, so we&#x27;re looking at several more comparisons here. Um, specifically which one of the two options that were considering in each comparison contains mawr, Adam? All right, so the 1st 1 we&#x27;ve got 12 grams of hydrogen versus 12 grams of carbon, 12 grams of carbon. That&#x27;s about one mole, 12 grams of hydrogen. That&#x27;s about 12 moles. So we&#x27;re gonna have, uh, that much more hydrogen hydrogen is gonna be more numerous in terms of atoms. So, too, um, we&#x27;re looking at 27 grams of aluminum versus 27 grams of iron. Aluminum has a lower Moeller mess than iron does. So for the same weight, there&#x27;s gonna be more Adams of aluminum. Third comparison, 40 grams of calcium versus 40 grams of sodium. The sodium has a lower bowl of mass than calcium. So for the same mass, there&#x27;s gonna be more sodium. Four, we&#x27;ve got 40 grams of calcium again or 60 grams of things. This is where we&#x27;re gonna have to take a look at the period table. And we can help that, um, from the periodic table. Um, thinking. Look at the periodic table. We see that zinc has a molar mass of 65 and calcium has a molar mass of about 40 grams per mole, so 60 little less than 65 grand&#x27;s from all. So we&#x27;re going to say that calcium barely edges out. Um, zinc here, in terms of the number of atoms, Uh, for the next comparison, we are comparing, um, 10 brands of lithium versus 100 grams of lead. So taking a look at the periodic table again, see that the molar mass of lead is about 207 rams for more, and the molar mass of lithium is about 6.9 grams for more. So for 100 grams of lead that is less than its more mass. And 10 grams of lithium is more than its molar mass. So we&#x27;re going to say that we have Mawr Adams of lithium than we do. Adams of Lead for this compares, and that&#x27;s it.

in this video, we will do few problem sets regarding convergence. And our conversion is on laws two grams and atoms to Gramps. Right? So first we will write the basic formula which we already know That is We know one more is equal to must in grands. Well, we&#x27;re grands in one more I&#x27;ll reconsider. This is Gladys. More low mass, right? So this is the formula. So one more is equal to mosque in grams divided by grams in one mole which is Carless molar mass off the specific element. Now other requirement is grants were provided the number off moles and we want to convert it into grams. So what we can do? We will multiply the number off moles into Moller Moss. So this formal I will change into so we&#x27;ll just multiply this tome into this so we can write it down. Must in Grands is equal. Joe, number off mourns into molar mass. So we&#x27;re gonna use this farm with right? So let&#x27;s do over first problem set. So we have given one more. Oh, I need you. So we have provided one mole off, lead him and we want to convert it into grants so over answer will be no mas in grands. First this number off Moore&#x27;s that is one and next ist Moeller must Smolar Mars Awfully, Tim iss 6.94 So answer will be 6.94 grass. Right? So according to this formula number off molds one molar mass 6.94 kind of our answer will be 6.94 grams. Let&#x27;s do the 2nd 1 again. We have given one moral off. Yeah, I assume so. Answer will be number off moons. That is one into Moeller Mosque. That is 29 19 It an answer will be 29.98 Gramps. Simple right. Number off moans into Moeller Moss. That&#x27;s still next one and her. We have provided one more. Oh, girl, She, um Right. So for one more off, can she, um answer, baby. One in two more months off calcium, that is 40 point Dio eight. So we will get over answered and grams 41 08 grams. Right. So easy. We have been awarding one more into Gramps. That&#x27;s do next. One next were provided with one mole off item. One more. Oh, I so it would be one into 55 1 You do fine. And underway. We 55 wine, 85 gram. So all the full problem said we were provided with number off malls. Wimmer deploying number off moles with the polar mask. And we caught over answering. Gramps, no next conversion is so. This is done here. Next, we will gonna work atoms into Gramps atoms. Two grants. How we can do that. So we know. First, we American word atoms doing Moore&#x27;s and then do Grams. So first we will follow First step that this active me two walls and then we will convert it into grams. No, let&#x27;s see over first question. Okay, so we are provided with six. Find zeal to to into 10 to power 23 actives. Oh, I&#x27;ve so if we can remember, this number is Karlis Abou Can&#x27;t remember. And Reno one Mo is equal to six point Tzeitel to to into 10 to power 23 Adams. Right. So one mole is equal to this number. We just call us ever Cottrill number. So if we&#x27;re provided with 6.2 into 10 to power 23 atoms off carbon that means it is equal. Do one more. Oh, got Right now we convert. It ended Moore&#x27;s and now we can easily convert into clam. So one into 12. 101 So we will get drilled. One Zito, one grass. Right? So we can water act IMS into moles. That is one more. And then we will keep, like mold with the molar mass. And that is over answering. Gramps, let&#x27;s do the second problem. Set game React provider with 610 22 into 10. Raise to power 23 act IMS Oh, let&#x27;s see the question. So, um, let me predict this. Yeah, So Riyadh provided with six point zeal. Oh, that&#x27;s a reas adult. So this is 2nd 1 six point Tzeitel to to into 10 to power 23 act IMS off silver. Right And again, we know this is our cattle number, and this number is equal to one mole. So we have one more. Oh, silver, right. And then we can multiply one into Moeller months off silver. That is one point Asari 107 point a seven Graham and over answer will be one point. So it&#x27;s it&#x27;s not grams it is Grandpa more? Yeah. So your answer will be 10 seven point 87 grounds. Okay, Now let&#x27;s revise. This whole time we want broken world moods into grams and Adams into grants. So the basic formalize one more is equal to mass in grams. Let&#x27;s mention the units here. So Maassen Grands the unit is grants, right? And then when we talk about grams in one pool, which is smaller mass, the unit will be good at but more right so we can cancel the grams with each other and we will get over answer in moves. And now, since we&#x27;re converting moles into grams so we just multiply this denominated down with the bulls. So mass in grams, busy courting number off morals into Moeller must. So for all we just provided, like one mole off medium one mole off culture and sorry, this is one more off aluminium. Okay, so we have one mole off medium, so we basically can work one more into the molar mass and we get over answering grams. So same for all we multiply number off malls with the molar mass and we get over answer and grants and again don&#x27;t forget the units. One mole, the united, small and floor um, molar mass unit is grants for more. And now we want to convert Adams into grants. It&#x27;s a two step process. First weaken work atoms to Moors and then moves to grams. We were provided that number off atoms off carbon. Ours explain 0 to 2 into 10 to power 23 which is almost We&#x27;re just not almost, which is exactly equal to one more off carbon. And we know that from here because one mole is always equal to 6.2 into 10 to power 23 atoms. So we got one mole on, one more less will be applied with the Moeller mask and we get the comes and see him for the silver.

to figure out which of these two amounts have more Adams. We have to transform them into the units of atoms. So to do this, we can start with Let&#x27;s just start with iron and we can use its Moeller Mass, which can be found on the periodic table to first get a two moles so divided by its molar mass. 55.8 five grams per mole. This will cancel out the grams and leave you with a value of 0.537 moles. Then, to get this to Adams, use all the GA jurors. Number 6.2 to times 10 to the 23rd Adams per mole. The moles will cancel out, and you will be left with the amount of Adams, which is three point to three times 10 to the 20 second Adams of iron. Let&#x27;s do the same exact thing for our amount of sulfur. Sulfur is molar. Mass is 32 0.7 grams. Permal, this will cancel out the grams and give us moles at a value of 0.6 to 4. And then we can multiply by all the gods rose number. This will once again council out moles and leave us with a final answer of three point 76 times 10 the 22nd Adams of Soul. For now, we have to figure out which one of these two values we just calculated has more Adams because they&#x27;re both to the same power of 10. We can ignore that and just look which one is higher. And it would be between 3.23 versus 3.37 six. So which one has more? 3.23 or 3.76? I hope everyone says 3.76 which means that are two grams of sulfur that we started with has more Adams. So I circled our final answer, of which one has more Adams.
