Molar and molecular weight of BaO2

• Relative molecular weight of BaO2: 169.3258
• Molar mass of BaO2: 169.3258 g/mol (0.16933 kg/mol)

Calculation of the relative molecular and molar mass of BaO2

• Mr[BaO2] = Ar[Ba] + Ar[O] * 2 = 137.327 + 15.9994 * 2 = 169.3258
• Molar mass (kg/mol) = Mr[BaO2] : 1000 = 169.3258 : 1000 = 0.16933 kg/mol

BaO2: percent composition by element

• Barium (Ba) = 137.327 : 169.3258 * 100 = 81.102 %
• Oxygen (O) = 31.9988 : 169.3258 * 100 = 18.898 %
