Molar and molecular weight of WO2

• Relative molecular weight of WO2: 215.8388
• Molar mass of WO2: 215.8388 g/mol (0.21584 kg/mol)

Calculation of the relative molecular and molar mass of WO2

• Mr[WO2] = Ar[W] + Ar[O] * 2 = 183.84 + 15.9994 * 2 = 215.8388
• Molar mass (kg/mol) = Mr[WO2] : 1000 = 215.8388 : 1000 = 0.21584 kg/mol

WO2: percent composition by element

• Tungsten (W) = 183.84 : 215.8388 * 100 = 85.175 %
• Oxygen (O) = 31.9988 : 215.8388 * 100 = 14.825 %
