Molar and molecular weight of PbI2

• Molecular formula: PbI2 or I2Pb
• Relative molecular weight of PbI2: 461.00894
• Molar mass of PbI2: 461.00894 g/mol (0.46101 kg/mol)

Calculation of the relative molecular and molar mass of PbI2

• Mr[PbI2] = Ar[I] * 2 + Ar[Pb] = 126.90447 * 2 + 207.2 = 461.00894
• Molar mass (kg/mol) = Mr[PbI2] : 1000 = 461.00894 : 1000 = 0.46101 kg/mol

PbI2: percent composition by element

• Iodine (I) = 253.80894 : 461.00894 * 100 = 55.055 %
• Lead (Pb) = 207.2 : 461.00894 * 100 = 44.945 %
