Molar and molecular weight of NaCl

• Molecular formula: NaCl or ClNa
• Relative molecular weight of NaCl: 58.44276928
• Molar mass of NaCl: 58.44276928 g/mol (0.05844 kg/mol)

Calculation of the relative molecular and molar mass of NaCl

• Mr[NaCl] = Ar[Cl] + Ar[Na] = 35.453 + 22.98976928 = 58.44276928
• Molar mass (kg/mol) = Mr[NaCl] : 1000 = 58.44276928 : 1000 = 0.05844 kg/mol

NaCl: percent composition by element

• Chlorine (Cl) = 35.453 : 58.44276928 * 100 = 60.663 %
• Sodium (Na) = 22.98976928 : 58.44276928 * 100 = 39.337 %
