Molar and molecular weight of Br2O

• Relative molecular weight of Br2O: 175.8074
• Molar mass of Br2O: 175.8074 g/mol (0.17581 kg/mol)

Calculation of the relative molecular and molar mass of Br2O

• Mr[Br2O] = Ar[Br] * 2 + Ar[O] = 79.904 * 2 + 15.9994 = 175.8074
• Molar mass (kg/mol) = Mr[Br2O] : 1000 = 175.8074 : 1000 = 0.17581 kg/mol

Br2O: percent composition by element

• Bromine (Br) = 159.808 : 175.8074 * 100 = 90.899 %
• Oxygen (O) = 15.9994 : 175.8074 * 100 = 9.101 %
