Molar and molecular weight of Br3Y

• Molecular formula: Br3Y or YBr3
• Relative molecular weight of Br3Y: 328.61785
• Molar mass of Br3Y: 328.61785 g/mol (0.32862 kg/mol)

Calculation of the relative molecular and molar mass of Br3Y

• Mr[Br3Y] = Ar[Br] * 3 + Ar[Y] = 79.904 * 3 + 88.90585 = 328.61785
• Molar mass (kg/mol) = Mr[Br3Y] : 1000 = 328.61785 : 1000 = 0.32862 kg/mol

Br3Y: percent composition by element

• Bromine (Br) = 239.712 : 328.61785 * 100 = 72.946 %
• Yttrium (Y) = 88.90585 : 328.61785 * 100 = 27.054 %
