Faraday's First Law

The following...

Question

The following cell has a potential of 0.55 V at 25 $^{o}$ C.
$P t (s) | H_{2} (1 a t m) | H^{+} (? M) | | C l^{-} (1 M) | H g_{2} C l_{2} (s) | H g (l)$
What is the pH of the solution in the anodic chamber? $E_{C l^{-} / H g_{2} C l_{2} / H g} = 0.28 V$
