Answer: g/mol

Step-by-step explanation:

The gram formula mass of CuSO 4 is 159.60 g/mol

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

CuSO 4 : 63.546 g/mol + 32.06 g/mol + 63.996 g/mol = 159.60 g/mol (rounded to two decimal places)
