• Molar mass of Cl2O8Pb: 406.1012 g/mol (0.4061 kg/mol)

Calculation of the relative molecular and molar mass of Cl2O8Pb

• Mr[Cl2O8Pb] = Ar[Cl] * 2 + Ar[O] * 8 + Ar[Pb] = 35.453 * 2 + 15.9994 * 8 + 207.2 = 406.1012
• Molar mass (kg/mol) = Mr[Cl2O8Pb] : 1000 = 406.1012 : 1000 = 0.4061 kg/mol

Cl2O8Pb: percent composition by element
