Molar and molecular weight of PoCl2

• Molecular formula: PoCl2 or Cl2Po
• Relative molecular weight of PoCl2: 279.8884
• Molar mass of PoCl2: 279.8884 g/mol (0.27989 kg/mol)

Calculation of the relative molecular and molar mass of PoCl2

• Mr[PoCl2] = Ar[Cl] * 2 + Ar[Po] = 35.453 * 2 + 208.9824 = 279.8884
• Molar mass (kg/mol) = Mr[PoCl2] : 1000 = 279.8884 : 1000 = 0.27989 kg/mol

PoCl2: percent composition by element

• Chlorine (Cl) = 70.906 : 279.8884 * 100 = 25.334 %
• Polonium (Po) = 208.9824 : 279.8884 * 100 = 74.666 %
