• Molar mass of NH4HSO4: 115.109 g/mol (0.11511 kg/mol)

Calculation of the relative molecular and molar mass of NH4HSO4

• Mr[NH4HSO4] = Ar[H] * 5 + Ar[N] + Ar[O] * 4 + Ar[S] = 1.00794 * 5 + 14.0067 + 15.9994 * 4 + 32.065 = 115.109
• Molar mass (kg/mol) = Mr[NH4HSO4] : 1000 = 115.109 : 1000 = 0.11511 kg/mol

NH4HSO4: percent composition by element

• Hydrogen (H) = 5.0397 : 115.109 * 100 = 4.378 %
• Nitrogen (N) = 14.0067 : 115.109 * 100 = 12.168 %
• Oxygen (O) = 63.9976 : 115.109 * 100 = 55.597 %
• Sulfur (S) = 32.065 : 115.109 * 100 = 27.856 %
