Molar and molecular weight of Bi

• Relative molecular weight of Bi: 208.9804
• Molar mass of Bi: 208.9804 g/mol (0.20898 kg/mol)

Calculation of the relative molecular and molar mass of Bi

• Mr[Bi] = Ar[Bi] = 208.9804 = 208.9804
• Molar mass (kg/mol) = Mr[Bi] : 1000 = 208.9804 : 1000 = 0.20898 kg/mol
