Molar and molecular weight of OPo

• Molecular formula: OPo or PoO
• Relative molecular weight of OPo: 224.9818
• Molar mass of OPo: 224.9818 g/mol (0.22498 kg/mol)

Calculation of the relative molecular and molar mass of OPo

• Mr[OPo] = Ar[O] + Ar[Po] = 15.9994 + 208.9824 = 224.9818
• Molar mass (kg/mol) = Mr[OPo] : 1000 = 224.9818 : 1000 = 0.22498 kg/mol

OPo: percent composition by element

• Oxygen (O) = 15.9994 : 224.9818 * 100 = 7.111 %
• Polonium (Po) = 208.9824 : 224.9818 * 100 = 92.889 %
