Molar and molecular weight of Br3Fe

• Molecular formula: Br3Fe or FeBr3
• Relative molecular weight of Br3Fe: 295.557
• Molar mass of Br3Fe: 295.557 g/mol (0.29556 kg/mol)

Calculation of the relative molecular and molar mass of Br3Fe

• Mr[Br3Fe] = Ar[Br] * 3 + Ar[Fe] = 79.904 * 3 + 55.845 = 295.557
• Molar mass (kg/mol) = Mr[Br3Fe] : 1000 = 295.557 : 1000 = 0.29556 kg/mol

Br3Fe: percent composition by element

• Bromine (Br) = 239.712 : 295.557 * 100 = 81.105 %
• Iron (Fe) = 55.845 : 295.557 * 100 = 18.895 %
