Molar and molecular weight of WO2Br2

• Relative molecular weight of WO2Br2: 375.6468
• Molar mass of WO2Br2: 375.6468 g/mol (0.37565 kg/mol)

Calculation of the relative molecular and molar mass of WO2Br2

• Mr[WO2Br2] = Ar[W] + Ar[O] * 2 + Ar[Br] * 2 = 183.84 + 15.9994 * 2 + 79.904 * 2 = 375.6468
• Molar mass (kg/mol) = Mr[WO2Br2] : 1000 = 375.6468 : 1000 = 0.37565 kg/mol
