Question

How many hydrogen atoms are there in 0.020 moles of C2H5OH

Answer 1

Hiya!

Im a little rusty so correct me if I'm wrong 

With 0.020 moles, multiply by the number of hydrogen atoms

0.20 x 5 = 0.1

1.00 moles of C2H5OH(Ethanol) = 6.02x10^23 


0.1 moles/ 1.00 x 6.02x10^23 = 6.02x10^22

(note: if this is from an iB chemistry book, especially at higher level, there may have been a typo for this answer! as this method has given correct results for later questions).

But do correct me if I'm wrong!
