What is the mass in grams of 6.022×1023 atoms of mass 16.00 amu?

Question

anonymous · Answer

I divided 16 into Avogadros # and got 2.657 times 10^-23

anonymous · Answer

But it says it's wrong..

aaronq · Answer

you know that $6.022×10^{23}$ is "a mole" (avogadros number) right?

aaronq · Answer

if you have 1 mole of atoms that weigh 16 amu, then the mass in grams is 16 g.

I thought I was supposed to divide it.. Your answer was right! Thank you zoo much again.. and sorry for the stupid questions! Hahaha.. They become so obvious once I get the right answer.. Haha. THANK YOUUUU!!!(:

aaronq · Answer

it's weird working in "amu" units. you can essentially say that if you have 1 moles of something that weighs 1 amu, then it weight 1 gram. Similarly, if you had 2 moles, then you have 2 grams. Hope this helped, and you're welcome !
