Molar and molecular weight of CuWO4

• Relative molecular weight of CuWO4: 311.3836
• Molar mass of CuWO4: 311.3836 g/mol (0.31138 kg/mol)

Calculation of the relative molecular and molar mass of CuWO4

• Mr[CuWO4] = Ar[Cu] + Ar[W] + Ar[O] * 4 = 63.546 + 183.84 + 15.9994 * 4 = 311.3836
• Molar mass (kg/mol) = Mr[CuWO4] : 1000 = 311.3836 : 1000 = 0.31138 kg/mol

CuWO4: percent composition by element

• Copper (Cu) = 63.546 : 311.3836 * 100 = 20.408 %
