Molar and molecular weight of PbCl2

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

Calculation of the relative molecular and molar mass of PbCl2

• Mr[PbCl2] = Ar[Cl] * 2 + Ar[Pb] = 35.453 * 2 + 207.2 = 278.106
• Molar mass (kg/mol) = Mr[PbCl2] : 1000 = 278.106 : 1000 = 0.27811 kg/mol

PbCl2: percent composition by element

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