Molar and molecular weight of CaWO4

• Relative molecular weight of CaWO4: 287.9156
• Molar mass of CaWO4: 287.9156 g/mol (0.28792 kg/mol)

Calculation of the relative molecular and molar mass of CaWO4

• Mr[CaWO4] = Ar[Ca] + Ar[W] + Ar[O] * 4 = 40.078 + 183.84 + 15.9994 * 4 = 287.9156
• Molar mass (kg/mol) = Mr[CaWO4] : 1000 = 287.9156 : 1000 = 0.28792 kg/mol

CaWO4: percent composition by element

• Calcium (Ca) = 40.078 : 287.9156 * 100 = 13.92 %
• Tungsten (W) = 183.84 : 287.9156 * 100 = 63.852 %
• Oxygen (O) = 63.9976 : 287.9156 * 100 = 22.228 %
