Problem $4(15$ points$)$:

An electrochemical cell is composed of pure copper and pure lead electrodes immersed in

solutions their respective divalent ions. For a $0\mathrm{.}6$ M concentration of $C{u}^{2+},$ the lead electrode is

oxidized, yielding a cell potential of $0\mathrm{.}507$ V $.$ Calculate the concentration of $P{b}^{2+}$ ions if the

temperature is $25C.($Use the tables on page $11$ in the PDF notes for Topic I$-2$
