One solution contains 1.569 mg of CoSO4 (155.0 g/mol) per milliliter. By showing your entire process, Calculate:

a) the volume of 7.840 x 10-3 M EDTA necessary to titrate CO2+ in 25.00 mL of this solution;

b) the volume of Zn2+ 9.275x10-3 M required to titrate excess EDTA after the addition of 50.00 mL of 7.840x10-3 M EDTA in 25.00 mL of the initial COSO4 solution;

c) the volume of 7.840x10-3 M EDTA needed to titrate Zn2+ displaced by CO2+ after adding an unmeasured excess of ZnY2- to 25.00 mL of the initial COSO4 solution. The reaction is:
CO2+ + ZnY2- -- COY2- + Zn2+
