Calculation of the relative molecular and molar mass of Ca(HSO4)2

• Mr[Ca(HSO4)2] = Ar[H] * 2 + Ar[Ca] + Ar[O] * 8 + Ar[S] * 2 = 1.00794 * 2 + 40.078 + 15.9994 * 8 + 32.065 * 2 = 234.21908
• Molar mass (kg/mol) = Mr[Ca(HSO4)2] : 1000 = 234.21908 : 1000 = 0.23422 kg/mol

Ca(HSO4)2: percent composition by element

• Hydrogen (H) = 2.01588 : 234.21908 * 100 = 0.861 %
• Calcium (Ca) = 40.078 : 234.21908 * 100 = 17.111 %
• Oxygen (O) = 127.9952 : 234.21908 * 100 = 54.648 %
• Sulfur (S) = 64.13 : 234.21908 * 100 = 27.38 %
