32g c2h3o2 to mol

Question

How am I supposed to convert, I'm so lost..

Answer 1

Divide the mass in grams of C₂H₃O₂ by the molecular weight (in grams per mole) of C₂H₃O₂.  That will give the number of moles.  If you do not know the molecular weight of C₂H₃O₂, look up the atomic weights (in grams per mole) of C, H, and O, and add them as

 

2(C) + 3(H) + 2(O).

 

That gives the molecular weight of C₂H₃O₂.
