Molar and molecular weight of PbF2

• Molecular formula: PbF2 or F2Pb
• Relative molecular weight of PbF2: 245.1968064
• Molar mass of PbF2: 245.1968064 g/mol (0.2452 kg/mol)

Calculation of the relative molecular and molar mass of PbF2

• Mr[PbF2] = Ar[F] * 2 + Ar[Pb] = 18.9984032 * 2 + 207.2 = 245.1968064
• Molar mass (kg/mol) = Mr[PbF2] : 1000 = 245.1968064 : 1000 = 0.2452 kg/mol

PbF2: percent composition by element

• Fluorine (F) = 37.9968064 : 245.1968064 * 100 = 15.496 %
• Lead (Pb) = 207.2 : 245.1968064 * 100 = 84.504 %
