An alloy of Pb-Ag weighing 1.08 g was dissolved in dilute$\mathrm{H}\mathrm{N}{\mathrm{O}}_3$and the volume made to 100 mL. A silver electrode was dipped in the solution and the emf of the cell set-up, Pt(s),${\mathrm{H}}_2\left(\mathrm{g}\right)\left|{\mathrm{H}}^{+}\right(1\text{M}\left)\right|\left|\text{A}{\text{g}}^{+}\right(\mathrm{a}\mathrm{q}\left)\mathrm{A}\mathrm{g}\right(\mathrm{s})$was 0.62 V. If${\mathrm{E}}_{\mathrm{c}\mathrm{e}\mathrm{l}\mathrm{l}}^{\mathrm{o}}$is 0.80 V, what is the percentage of Ag in the alloy? (At$25°\mathrm{C}$, RT/F = 0.06)
