Question

Suppose you have 50 grams of copper and 50 grams of gold. Which sample has more atoms? Explain your thinking.

Ethan Fuhrman · Accepted Answer

All right. So you have two samples of metal, you have 50 grams of copper, and you have 50 grams of gold. Um, but you want to know how many? Uh, I&#x27;m sorry. You want to know which sample contains more Adams? So we know that gold each gold Adam weighs about 3.27 times 10 to the bias. 22nd grams and copper. Adam&#x27;s way. About 1.5 times 10 to the minus 20 seconds. Grams on it. Um, So if you have 50 grand&#x27;s of each metal but each metal or each the atom of each metal ways different amounts, uh, each copper Adam about 1/3 the size of, uh, gold Adam on average. Um, you&#x27;ll have about three times as many copper Adams as he would the number of gold Adams. So in this case, you would have more copper at

Ricajoy Montero · Answer

question 103 is asking us from which of these has more Adams one more off silver or one more of gold and according to have a gorgeous number, one more equals to six point you 22 times 2 23 Adams. And the beauty of the average garters number is that this number right here is constant. It doesn&#x27;t matter what compound you have or what element you have. One more would have 6.22 times 23 Adams or time stand to 23. So for that reason, you could say that one more of silver I should have the same number of Adam&#x27;s. This one more gold, because again you have Roger&#x27;s number. It&#x27;s constant for any a limit or any compound.

Laurent Bergeron · Answer

thanks. So in this exercise were asked to find a number off gold atoms in 27.5 grams of it, and then to compare with the same mass of silver. For this problem, we need to look into the periodic table so golden the predictable is a U good. You have to make number 79. And we conceded at the MK Mass of gold is 196.97 you one u is 1.66 times 10 to the minus 27 kilograms. So the weight of one particle of gold, it&#x27;s gonna be 196.97 times this number here. Right? So we will do everything in kilogram so that the units can cancel each other. 27.5 gram of gold is 0.0. Shoot seven five kilograms and then we will divide by the atomic mass of one particle. This will give us the number. It&#x27;s practical. So the mass for one particle of gold is as we send the previous tab one in 6.966 I think I just used 97 Well, let&#x27;s use other numbers here 966569 That&#x27;s probably throwing numbers. You don&#x27;t need to use as many. No reason to this mall things you, which is 1.66 times 10 to the minus 27 kilograms for gold. So I will note a you this one practical of cold or number. This gives us 8.4 one times 10 to 22. No grift vertical. So that&#x27;s a lot of particles in this smaller ring of gold. We can do the same for silver. So again we have, actually, we can probably use this here. So for a silver, I&#x27;m gonna use a different color. The only thing that changes is this number here and for silver we have instead of 196 107 point it&#x27;s so let&#x27;s just use those two numbers here after additional 100 and 7.87 use. So we use the same factor for did you get to youth? And then this gives us a different result. Off one point five four. I&#x27;m stem to the 20 treatise thing. So there is There are more silver particles. Then go particles for the same mess of material. And this makes sense because an individual act, um, of silver, which less than an atom of gold. And so if you take the same mass, you will need Maur atoms of silver to make up for it. So they asked us to compare between them. So when we do, it would be to divide them and see, um, their issue of the two. So if we wish you it, get about this if we reach you us. The number off gold particle divided by the number if several particles, for example, eight point for one times 10 to 22 divided by 1.54 times 10 to the 20 tree. This is equal to zero point 548 And that&#x27;s the answer to give in, um in the manual, which is the ratio between the number of gold particle in the number of silver particles that there&#x27;s about twice as many practical in their suffering. That&#x27;s it for this one

so say you&#x27;ve got a sample of rice and you&#x27;ve got a sample of being field away. Both of them. Turns out they&#x27;re both 50 grams in math. Uh, however eating to know how many grains of rice and how maney beans. Yeah. So which do we think there would be more rice or the being? Well, if he said rice, he would be correct. So because rice or smaller, uh, there would be more individual rice grains and there would be individual beans for the same math. And we can apply this logic to other things as well the specialty in chemistry. So if you have, um, the same mass of, say, lithium and barium, you&#x27;re gonna have Mawr Adams of lithium because it&#x27;s a lot smaller in Mass and a lot smaller in size. Then it is for each barium Adam, for example,

David Collins · Answer

if we have 15 grams of a bunch of different elements than the one that has the smallest moulder mass is gonna be the one that has the greatest number of moles of the greatest number of atoms. Because the smaller Moeller Mass means you have let less mass required toe have a mole. So the largest number of Adams, then, out of these examples will be the one with the lowest muller mass or your on.

Salamat Ali · Answer

for a given Mass, which is a 12 point five gram. The number of moles is equal to given mass, divided by the molar mass, which is 63.546 for the copper. This year&#x27;s US the number of moles off 0.1967 moles but be the number off items can be found by an musical. The number of items. They&#x27;re these, um, all times if I got those number So malls we have is a report 1967 times of our God does number that is zero for 6 36.0 to 2 time sprint forward 23 When you find these two numbers gives us the number of items that is 1.1845 thyme scented power. 23 a Tums
