total hardness = (4.24 + 2.12) x 10-3 mol/L = 6.36 x 10-3 M or 636 mg/L of CaCO 3 total alkalinity = (4.02 + 0.02) x 10-3 mol/L = 4.04 x 10 M or 202 mgL of CaCO 3 Therefore the permanent hardness (that not removed by boiling) is given by 434 mg/L of CaCO 3 and the temporary hardness is 202 mg/L CaCO 3.
