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'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's way. About 1.5 times 10 to the minus 20 seconds. Grams on it. Um, So if you have 50 grand'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'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
