The gram formula mass of CuSO4 is 159.60 g/mol

Explanation:

Multiply the subscript for each element by its molar mass (atomic mass on periodic table in g/mol). Then add the results. This will give you the molar mass of the compound (mass of 1 mole).

Cu:(1×63.546 g/mol)=63.546 g/mol

S:(1×32.065 g/mol)=32.06 g/mol

O:(4×15.999 g/mol)=63.996 g/mol

CuSO4:63.546 g/mol+32.06 g/mol+63.996 g/mol=159.60 g/mol (rounded to two decimal places)
