Molar and molecular weight of WBr4

• Relative molecular weight of WBr4: 503.456
• Molar mass of WBr4: 503.456 g/mol (0.50346 kg/mol)

Calculation of the relative molecular and molar mass of WBr4

• Mr[WBr4] = Ar[W] + Ar[Br] * 4 = 183.84 + 79.904 * 4 = 503.456
• Molar mass (kg/mol) = Mr[WBr4] : 1000 = 503.456 : 1000 = 0.50346 kg/mol
