Molar and molecular weight of CuS

• Relative molecular weight of CuS: 95.611
• Molar mass of CuS: 95.611 g/mol (0.09561 kg/mol)

Calculation of the relative molecular and molar mass of CuS

• Mr[CuS] = Ar[Cu] + Ar[S] = 63.546 + 32.065 = 95.611
• Molar mass (kg/mol) = Mr[CuS] : 1000 = 95.611 : 1000 = 0.09561 kg/mol

CuS: percent composition by element

• Copper (Cu) = 63.546 : 95.611 * 100 = 66.463 %
• Sulfur (S) = 32.065 : 95.611 * 100 = 33.537 %
