Molar and molecular weight of HgPo

• Relative molecular weight of HgPo: 409.5724
• Molar mass of HgPo: 409.5724 g/mol (0.40957 kg/mol)

Calculation of the relative molecular and molar mass of HgPo

• Mr[HgPo] = Ar[Hg] + Ar[Po] = 200.59 + 208.9824 = 409.5724
• Molar mass (kg/mol) = Mr[HgPo] : 1000 = 409.5724 : 1000 = 0.40957 kg/mol

HgPo: percent composition by element

• Mercury (Hg) = 200.59 : 409.5724 * 100 = 48.975 %
• Polonium (Po) = 208.9824 : 409.5724 * 100 = 51.025 %
