Calculate the value for total water hardness (amount of Ca + Mg). This will be reported in terms of CaCO3 in mg/L. The moles of (Ca+Mg) is equal to the moles of EDTA used in the titration. Multiply the molarity of the EDTA by the volume in L of EDTA used to get the moles. Then convert the moles to mass using the molar mass of CaCO3. Finally convert your answer to mg and divide by the total volume in...
