Question

Quizplus · Accepted Answer

The formula for copper(II) sulfate is CuSO4. To calculate the molar mass, we need to add up the atomic masses of all the atoms in one mole of the compound.

CuSO4 molar mass:  
Atomic mass of Cu = 63.55 g/mol 
Atomic mass of S = 32.06 g/mol 
Atomic mass of O (4 x atomic mass of O) = 4 x 16.00 g/mol = 64.00 g/mol

Total molar mass = 63.55 g/mol + 32.06 g/mol + 64.00 g/mol = 159.61 g/mol

So, the molar mass of copper(II) sulfate is 159.6 g/mol, which is answer choice D.
