Calcium in powdered milk is determined by dry ashing a 3.00g sample then titrating the calcium with 12.10mL EDTA solution. The EDTA was standardized by titrating 10.00mL of a Zn solution by dissolving 0.632g Zn metal in acid and dilution to 1.00L (10.80 mL EDTA required for titration). What is the concentration of Ca in the powdered milk in ppm?
