Molar and molecular weight of W2C

• Relative molecular weight of W2C: 379.6907
• Molar mass of W2C: 379.6907 g/mol (0.37969 kg/mol)

Calculation of the relative molecular and molar mass of W2C

• Mr[W2C] = Ar[W] * 2 + Ar[C] = 183.84 * 2 + 12.0107 = 379.6907
• Molar mass (kg/mol) = Mr[W2C] : 1000 = 379.6907 : 1000 = 0.37969 kg/mol

W2C: percent composition by element

• Tungsten (W) = 367.68 : 379.6907 * 100 = 96.837 %
• Carbon (C) = 12.0107 : 379.6907 * 100 = 3.163 %
