Molar and molecular weight of Rn

• Relative molecular weight of Rn: 222.0176
• Molar mass of Rn: 222.0176 g/mol (0.22202 kg/mol)

Calculation of the relative molecular and molar mass of Rn

• Mr[Rn] = Ar[Rn] = 222.0176 = 222.0176
• Molar mass (kg/mol) = Mr[Rn] : 1000 = 222.0176 : 1000 = 0.22202 kg/mol
