Question

In the cell $\mathrm{Pt}(\mathrm{s})\left|\mathrm{H}_2(\mathrm{~g}, 1 \mathrm{bar})\right| \mathrm{HCl}(\mathrm{aq})|\mathrm{AgCl}(\mathrm{s})| \mathrm{Ag}(\mathrm{s}) \mid \mathrm{Pt}(\mathrm{s})$ the cell potential is 0.92 V when a $10^{-6}$ molal HCl solution is used. The standard electrode potential of $\left(\mathrm{AgCl} / \mathrm{Ag} / \mathrm{Cl}^{-}\right)$electrode is:
$\left\{\right.$ Given, $\frac{2.303 R T}{F}=0.06 \mathrm{~V}$ at 298 K$\}$
