Chemistry Question!

OpenStudy (unbelievabledreams):

How many moles of atoms are contained in 22.1 g of CH3OH?

OpenStudy (anonymous):

so you're just trying to find the number of moles?

OpenStudy (anonymous):

The molar mass of CH3OH is 32.04 g/mol

OpenStudy (anonymous):

so to get the moles, divide 22.1/32.04

OpenStudy (anonymous):

This gives 0.69 moles of CH3OH

OpenStudy (unbelievabledreams):

I believe so. But it said incorrect. The hint: Did you multiply or divide by Avogadro's number? I am confused

OpenStudy (anonymous):

are you trying to find the number of atoms? the question is unclear.

OpenStudy (unbelievabledreams):

I believe so.

OpenStudy (anonymous):

ok, multiply the number of moles we got by avagadro's number

OpenStudy (anonymous):

4.1538x10^23 atoms
