Molar and molecular weight of WBr5

• Relative molecular weight of WBr5: 583.36
• Molar mass of WBr5: 583.36 g/mol (0.58336 kg/mol)

Calculation of the relative molecular and molar mass of WBr5

• Mr[WBr5] = Ar[W] + Ar[Br] * 5 = 183.84 + 79.904 * 5 = 583.36
• Molar mass (kg/mol) = Mr[WBr5] : 1000 = 583.36 : 1000 = 0.58336 kg/mol

WBr5: percent composition by element

• Tungsten (W) = 183.84 : 583.36 * 100 = 31.514 %
• Bromine (Br) = 399.52 : 583.36 * 100 = 68.486 %
