• Molar mass of NaHSO3: 104.06090928 g/mol (0.10406 kg/mol)

Calculation of the relative molecular and molar mass of NaHSO3

• Mr[NaHSO3] = Ar[H] + Ar[Na] + Ar[O] * 3 + Ar[S] = 1.00794 + 22.98976928 + 15.9994 * 3 + 32.065 = 104.06090928
• Molar mass (kg/mol) = Mr[NaHSO3] : 1000 = 104.06090928 : 1000 = 0.10406 kg/mol

NaHSO3: percent composition by element

• Hydrogen (H) = 1.00794 : 104.06090928 * 100 = 0.969 %
• Sodium (Na) = 22.98976928 : 104.06090928 * 100 = 22.093 %
• Oxygen (O) = 47.9982 : 104.06090928 * 100 = 46.125 %
• Sulfur (S) = 32.065 : 104.06090928 * 100 = 30.814 %
