14. A solution is prepared by adding 0.5590 g of powdered milk into a 5.0E+02 mL volumetric flask and adding 30 mL of 1.0 M KCL and diluting to volume with DI water. The concentration of a milk sample is determined to be 5.130x104 M Ca2+ based on linear regression analysis of calcium standard solutions. What is the concentration of Ca2+ in the milk sample (wt/wt %)? [MW Ca= 40.078 g/mole] O 0.110 1.84 6.75 6.746 0.4048 O 1.839 Submit Answer Incorrect. Tries 1/2 Previous Tries
