Molar and molecular weight of Cl2

• Relative molecular weight of Cl2: 70.906
• Molar mass of Cl2: 70.906 g/mol (0.07091 kg/mol)

Calculation of the relative molecular and molar mass of Cl2

• Mr[Cl2] = Ar[Cl] * 2 = 35.453 * 2 = 70.906
• Molar mass (kg/mol) = Mr[Cl2] : 1000 = 70.906 : 1000 = 0.07091 kg/mol
