Molar and molecular weight of PbCl4

• Molecular formula: PbCl4 or Cl4Pb
• Relative molecular weight of PbCl4: 349.012
• Molar mass of PbCl4: 349.012 g/mol (0.34901 kg/mol)

Calculation of the relative molecular and molar mass of PbCl4

• Mr[PbCl4] = Ar[Cl] * 4 + Ar[Pb] = 35.453 * 4 + 207.2 = 349.012
• Molar mass (kg/mol) = Mr[PbCl4] : 1000 = 349.012 : 1000 = 0.34901 kg/mol

PbCl4: percent composition by element

• Chlorine (Cl) = 141.812 : 349.012 * 100 = 40.632 %
• Lead (Pb) = 207.2 : 349.012 * 100 = 59.368 %
