Molar and molecular weight of PbBr2

• Molecular formula: PbBr2 or Br2Pb
• Relative molecular weight of PbBr2: 367.008
• Molar mass of PbBr2: 367.008 g/mol (0.36701 kg/mol)

Calculation of the relative molecular and molar mass of PbBr2

• Mr[PbBr2] = Ar[Br] * 2 + Ar[Pb] = 79.904 * 2 + 207.2 = 367.008
• Molar mass (kg/mol) = Mr[PbBr2] : 1000 = 367.008 : 1000 = 0.36701 kg/mol

PbBr2: percent composition by element

• Bromine (Br) = 159.808 : 367.008 * 100 = 43.543 %
• Lead (Pb) = 207.2 : 367.008 * 100 = 56.457 %
