Molar and molecular weight of HBrO2

• Molecular formula: HBrO2 or HOBrO
• Relative molecular weight of HBrO2: 112.91074
• Molar mass of HBrO2: 112.91074 g/mol (0.11291 kg/mol)

Calculation of the relative molecular and molar mass of HBrO2

• Mr[HBrO2] = Ar[H] + Ar[Br] + Ar[O] * 2 = 1.00794 + 79.904 + 15.9994 * 2 = 112.91074
• Molar mass (kg/mol) = Mr[HBrO2] : 1000 = 112.91074 : 1000 = 0.11291 kg/mol

HBrO2: percent composition by element

• Hydrogen (H) = 1.00794 : 112.91074 * 100 = 0.893 %
• Bromine (Br) = 79.904 : 112.91074 * 100 = 70.767 %
• Oxygen (O) = 31.9988 : 112.91074 * 100 = 28.34 %
