Molar and molecular weight of CO3Pb

• Molecular formula: CO3Pb or PbCO3
• Relative molecular weight of CO3Pb: 267.2089
• Molar mass of CO3Pb: 267.2089 g/mol (0.26721 kg/mol)

Calculation of the relative molecular and molar mass of CO3Pb

• Mr[CO3Pb] = Ar[C] + Ar[O] * 3 + Ar[Pb] = 12.0107 + 15.9994 * 3 + 207.2 = 267.2089
• Molar mass (kg/mol) = Mr[CO3Pb] : 1000 = 267.2089 : 1000 = 0.26721 kg/mol

CO3Pb: percent composition by element

• Carbon (C) = 12.0107 : 267.2089 * 100 = 4.495 %
• Oxygen (O) = 47.9982 : 267.2089 * 100 = 17.963 %
• Lead (Pb) = 207.2 : 267.2089 * 100 = 77.542 %
