Calculation of the relative molecular and molar mass of Mg(HCO3)2

• Mr[Mg(HCO3)2] = Ar[C] * 2 + Ar[H] * 2 + Ar[Mg] + Ar[O] * 6 = 12.0107 * 2 + 1.00794 * 2 + 24.305 + 15.9994 * 6 = 146.33868
• Molar mass (kg/mol) = Mr[Mg(HCO3)2] : 1000 = 146.33868 : 1000 = 0.14634 kg/mol

Mg(HCO3)2: percent composition by element

• Carbon (C) = 24.0214 : 146.33868 * 100 = 16.415 %
• Hydrogen (H) = 2.01588 : 146.33868 * 100 = 1.378 %
• Magnesium (Mg) = 24.305 : 146.33868 * 100 = 16.609 %
• Oxygen (O) = 95.9964 : 146.33868 * 100 = 65.599 %
