Question

Which has more moles of molecules, 1.0 g methanol, $\mathrm{CH}_{4} \mathrm{O},$ or 1.0 $\mathrm{g}$ ethanol, $\mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O} ?$

Okay, so here we&#x27;re comparing. Um, but number of moles of molecule. For two compounds, the 1st 1 is methanol or C H 38 and ethanol, which has a formula of C H three C H two. Okay. And they have muller masses of around 32 grams per mole and 45 grams per mole, respectively. Okay, so we have one gram of and we want to know which sample which one gram sample has the greater number of mold. So sense Methanol has a lower molar mass of, um, inherently compared to ethanol. For the same math, there&#x27;s going to be mawr molds of method all than there will be for ethanol. Since each molecule weighs less in grams per mole, then

10 grams of nitrogen will have more molecules than 10 grams of oxygen. This is because if you set up the calculation, we can just say that note the one has a greater number of moles. Also has the greater number of molecules because there are a set number of molecules animal, which is avocados, number for six for no 22 times 10 to the 23rd. So here, if we started 10 grams of end too, we can roughly approximate the Moler massive night shin to be 28 grams per mole. We do the same thing for oxygen. You get 10 grams of 02 You divide by 32 grams per mole. Here, we&#x27;ll find that the nation is definitely greater than the oxygen because dividing something by 28 will give a larger number than dividing something by 32. Sir, nitrogen will have a greater number of molecules in 10 grams than I

in this question of tenacity. Seven. Which of these containment grid is massive oxygen? All right, so in other cities have been the greatest mass of oxygen. Well, which I mean, which of these contain agrees? Minutes of oxygen. We first need to determined how many hostages are in the various compounds and ivy stated here and link that to the amount off malls. Are we given? Right, so, huh, We should know that mass is given by the more by the molar mass. All right, so we&#x27;re all doing much arithmetic here. All right, The first ethanol contains one oxygen. Uh, formic acid here contains two oxygen and water. Quentin&#x27;s only one oxygen by yourself to look at the mall&#x27;s right to have 10.75 more 0.60 and one. So the massive oxygen for decimal here simply can be derived by multiplying the morals of a 0.75 Bye. The officer. The one oxygen atom that we have here. So Ah, well, a massive walks in his 15.999 All right, this would approximately give us 11.999 Gramps, I didn&#x27;t stick the unit here, but this has units Mmm. The question and this is units, ground school move. So when I was all should be in grams. Do this do the same for the 2nd 1 which is formic acid. I have 0.60 move by 15.999 times two. Okay, because we have two oxygen&#x27;s for my guest. And that should give us 19 point 199 grams. Lastly for water, you just have one more and you know well, most Vulcans 15.999 Yeah, well, yeah, Grandpa. So what we can do here is which is 4999 So that should give us the 10.999 grams. So among these three 0.60 mole off former casted us the greatest massive oxygen.

so we want to know which contains the largest number of Marge&#x27;s moles of oxygen atoms from these three compounds. So we have one more of ethanol, which is C two h 50 h. One more of formic acid, which is H 20 to H and one mall of water, which is H 20 Now, in this case, for every one mole of C two h 50 age, we get one more of oxygen. For every one mole of formic acid, we get two moles of oxygen and for everyone, more of H 20 winning. That way we get one mole of oxygen. So therefore formic acid in has the largest number of mole how largest malls of

Ethan Fuhrman · Answer

Okay, so we&#x27;re looking at hot number of grams, uh, carbon molecules in one more of you of the following. So the first substance we&#x27;ve got nothing. C h four for the 2nd 1 We&#x27;ve got methanol. Eight 38 And for the 3rd 1 we&#x27;ve got ethanol. Eight three c 208 Okay, so we&#x27;re just looking at carbon in each of these. So methane has one carbon molecule, methanol, one carbon atom and ethanol to carbon. So we know that the molar mass of carbon is 12.11 grams per mole. So were, um, methanol. In each mole of methanol, there will be 12.11 grams for mole grams of carbon. And in one mole of methanol, there will be 12.11 grams of carbon as well. In one mole of ethanol, there will be two moles off carbon because there are two atoms of carbon. So two moles times 12.11 grams per mole gives us 24 0.0 to 2 grams of carbon

we have to fund the lumber. Most off the flooring are chemical compound. So the first woman keep isa caffeine. So we given the mass off giving is 20 milligram But we have the convert that to ah Graham. So it would be corresponding to ah still points. He was 20 and then we were divided More than mass off our caffeine, So ah, for caffeine. Um, well, you have to cope with them all the mass, So Ah, we have a comment on that. We have 1000 that we&#x27;re for ah, nine Trojans and that we have ah to also Jim. So if you find them on the muscle caffeine and ah, you should be able to solve stati the lumbar motion people for around one point All three time 10 10 miles four So, um then we quickly Teoh collated Move the mass Ah, off coffee And you should be a referee of roughly 34 grand per mole. So it is a pretty epic lumber. OK, move on to party. We have 2.72 time tender power, 21 molecule of f. You know So actually we can convert the lumber more que off? Ah ah! After new two number almost by Cynthia divider number Markkula by the every casual lumber So we&#x27;re 2.72 point 72 Time 10 to power or 21 divide by six point over two time. Ah, the Weber&#x27;s exploring or two time 10 to power 23. And then we should be able to find that I saw a rise 4.52 time 10 to power off that if we No. Okay, so Lastman lawyers, we have, ah, 1.5 gram off dry ice, so Ah, we&#x27;re going to take our, um master by the molar mass off dry eyes were becoming doubts I So we have ah, 1.5 divide by 44 then we should be able to find that is what they&#x27;re on 0.0 ce fel one. No,
