4. Calcium in powdered milk was determined by ashing a 1.500g sample and then titrating the calcium with EDTA solution. The volume of EDTA necessary for the titration was 12.09 mL. The EDTA was standardized by titrating 10.00 mL of a zinc solution prepared by digesting 0.6322 g of zinc metal in acid and diluting to 1.000 L. The volume of EDTA necessary for the standardization was 10.79 mL. What is the concentration of calcium in parts per million?
