No, you are correct. One mole contains Avogadro's number of molecules, 6.02 x 10^23, so 12.7 mol contains 12.7*6.02 x 10^23 molecules. It's possible that the answer key is wrong, or else you made a computational error. It could also be the case that you've misunderstood the question, and that the question you asked here is not the question that was actually posed to you.

I'm not completely certain without looking in the book, but I think you have to multiply 12.7 by 6.02 x 10 23(by the 23, I mean 23rd power)

divive 12.7 by Avogadros. remember 1 mol=1 molecule=6.22x10^23.

it is 12.7 x 6.02x10^23 = 7.64 x 10^24
if someone or something says that is wrong, then there is more to the question. like x moles oxygen atoms= ? molecules O2

Hmmm... I assumed the same as you. 6 times 10 to the 23rd

If its in an equation, you need to multiply by a mole ratio first.
