How do I determine the number of grams for the following Substance? 7.8 mol ZnSo4
4 answers
grams = mols x molar mass
1molZnSO4= 164.46gZnSO4( the molar mass)
7.8 mol ZnSO4* (164.46gZnSO4/1molZnSO4)
= 1259.388g ZnSO4
7.8 mol ZnSO4* (164.46gZnSO4/1molZnSO4)
= 1259.388g ZnSO4
I got 161.47g/mol for ZnSO4
Zn= 65.4094 g/mol
S= 32.065 g/mol
O= 4(15.999 g/mol)
Other than that your method for calculating is correct.

7.8mol ZnSO4 x 161.47g/mol= _________?
Using a calculator on the web I obtained 161.45 g/mol ZnSO4. I don't know it that site has the "latest" changes or not. I'm glad Christina caught that.
