Molar and molecular weight of Cl2Pb

• Molecular formula: Cl2Pb or PbCl2
• Relative molecular weight of Cl2Pb: 278.106
• Molar mass of Cl2Pb: 278.106 g/mol (0.27811 kg/mol)

Calculation of the relative molecular and molar mass of Cl2Pb

• Mr[Cl2Pb] = Ar[Cl] * 2 + Ar[Pb] = 35.453 * 2 + 207.2 = 278.106
• Molar mass (kg/mol) = Mr[Cl2Pb] : 1000 = 278.106 : 1000 = 0.27811 kg/mol

Cl2Pb: percent composition by element

• Chlorine (Cl) = 70.906 : 278.106 * 100 = 25.496 %
• Lead (Pb) = 207.2 : 278.106 * 100 = 74.504 %
