Molar and molecular weight of CuSO4

• Molecular formula: CuSO4 or CuO4S
• Relative molecular weight of CuSO4: 159.6086
• Molar mass of CuSO4: 159.6086 g/mol (0.15961 kg/mol)

Calculation of the relative molecular and molar mass of CuSO4

• Mr[CuSO4] = Ar[Cu] + Ar[O] * 4 + Ar[S] = 63.546 + 15.9994 * 4 + 32.065 = 159.6086
• Molar mass (kg/mol) = Mr[CuSO4] : 1000 = 159.6086 : 1000 = 0.15961 kg/mol

CuSO4: percent composition by element

• Copper (Cu) = 63.546 : 159.6086 * 100 = 39.814 %
• Oxygen (O) = 63.9976 : 159.6086 * 100 = 40.097 %
• Sulfur (S) = 32.065 : 159.6086 * 100 = 20.09 %
