magnesium hardness (mg/L) as CaCO, magnesium (mg/L) equivalent weight of CaCO, equivalent weight of magnesium x mg/L 9 mg/L 50.045 12.15 x = 37.1 mg/L Mg as Caco, Now, total hardness can be calculated using Equation 21.3: Total hardness (mg/L) = 69.9 mg/L + 37.1 mg/L = 107 mg/L as CaCO3 Determine the total hardness as ppm CaCO3 of a sample of water that has calcium content of 56 mg/L and magnesium content of 4.5 mg/L.
