A 100 mL sample of hard water is titrated with EDTA solution. The same amount of Mg^2+ is added as previously, and the volume of EDTA required is 17.64 mL. How many moles of EDTA are there in that volume? How many moles of Ca^2+ are there in the 100 mL of water? If the Ca^2+ comes from CaCO3, how many moles of CaCO3 are there in one liter of the water? How many grams CaCO3 per liter? Preluding answers: 0.005113 mol CaCO3 Molarity of Ca^2+ in 250 mL solution: 0.0206 M 5.12e^-4 mol Ca^2+ in 25.00 mL solution from above 27.56 mL EDTA needed to titrate Ca^2+ ion 5.12e^-4 mol EDT
