Molar and molecular weight of BrO2

• Relative molecular weight of BrO2: 111.9028
• Molar mass of BrO2: 111.9028 g/mol (0.1119 kg/mol)

Calculation of the relative molecular and molar mass of BrO2

• Mr[BrO2] = Ar[Br] + Ar[O] * 2 = 79.904 + 15.9994 * 2 = 111.9028
• Molar mass (kg/mol) = Mr[BrO2] : 1000 = 111.9028 : 1000 = 0.1119 kg/mol

BrO2: percent composition by element

• Bromine (Br) = 79.904 : 111.9028 * 100 = 71.405 %
• Oxygen (O) = 31.9988 : 111.9028 * 100 = 28.595 %
