A 1.3246 g sample was dissolved with 5.00 mL of concentrated HCl. The resulting solution was diluted with water to a total volume of 100.0 mL. A 25.00 mL aliquot of this solution was neutralized with NaOH and then 15.00 mL of 0.10 M ethylenediamine was added. The mixture was diluted to a total volume of 200.0 mL. This mixture was analyzed spectroscopically and determined to have a concentration of 1.56 ppm Co. What is the percent of cobalt in the original sample?
