Molar and molecular weight of O2Pb

• Molecular formula: O2Pb or PbO2
• Relative molecular weight of O2Pb: 239.1988
• Molar mass of O2Pb: 239.1988 g/mol (0.2392 kg/mol)

Calculation of the relative molecular and molar mass of O2Pb

• Mr[O2Pb] = Ar[O] * 2 + Ar[Pb] = 15.9994 * 2 + 207.2 = 239.1988
• Molar mass (kg/mol) = Mr[O2Pb] : 1000 = 239.1988 : 1000 = 0.2392 kg/mol

O2Pb: percent composition by element

• Oxygen (O) = 31.9988 : 239.1988 * 100 = 13.377 %
• Lead (Pb) = 207.2 : 239.1988 * 100 = 86.623 %
