Molar and molecular weight of Ra

• Relative molecular weight of Ra: 226.0254
• Molar mass of Ra: 226.0254 g/mol (0.22603 kg/mol)

Calculation of the relative molecular and molar mass of Ra

• Mr[Ra] = Ar[Ra] = 226.0254 = 226.0254
• Molar mass (kg/mol) = Mr[Ra] : 1000 = 226.0254 : 1000 = 0.22603 kg/mol
