Molar and molecular weight of MgWO4

• Relative molecular weight of MgWO4: 272.1426
• Molar mass of MgWO4: 272.1426 g/mol (0.27214 kg/mol)

Calculation of the relative molecular and molar mass of MgWO4

• Mr[MgWO4] = Ar[Mg] + Ar[W] + Ar[O] * 4 = 24.305 + 183.84 + 15.9994 * 4 = 272.1426
• Molar mass (kg/mol) = Mr[MgWO4] : 1000 = 272.1426 : 1000 = 0.27214 kg/mol

MgWO4: percent composition by element

• Magnesium (Mg) = 24.305 : 272.1426 * 100 = 8.931 %
• Tungsten (W) = 183.84 : 272.1426 * 100 = 67.553 %
• Oxygen (O) = 63.9976 : 272.1426 * 100 = 23.516 %
