Molar and molecular weight of I

• Relative molecular weight of I: 126.90447
• Molar mass of I: 126.90447 g/mol (0.1269 kg/mol)

Calculation of the relative molecular and molar mass of I

• Mr[I] = Ar[I] = 126.90447 = 126.90447
• Molar mass (kg/mol) = Mr[I] : 1000 = 126.90447 : 1000 = 0.1269 kg/mol
