Molar and molecular weight of HCl

• Relative molecular weight of HCl: 36.46094
• Molar mass of HCl: 36.46094 g/mol (0.03646 kg/mol)

Calculation of the relative molecular and molar mass of HCl

• Mr[HCl] = Ar[H] + Ar[Cl] = 1.00794 + 35.453 = 36.46094
• Molar mass (kg/mol) = Mr[HCl] : 1000 = 36.46094 : 1000 = 0.03646 kg/mol

HCl: percent composition by element

• Hydrogen (H) = 1.00794 : 36.46094 * 100 = 2.764 %
• Chlorine (Cl) = 35.453 : 36.46094 * 100 = 97.236 %
