A cell consisting of a saturated calomel electrode and a lead ion electrode developed a potential of -0.3257 V when immersed in a 60.00 mL lead solution of unknown concentration. A 10.00 mL addition of 0.02500 M lead standard solution caused the reduction potential to shift to -.2897 V. Calculate the molar concentration (in units mM) of lead in the sample. Please make sure to perform necessary calculations to have a final answer in mM.
