The activities of solids and liquids are takes as unity and at low concentrations, the activity of a solute is approximated to its molarity.
Th cell reaction will be
$Pt_{(s)} | H_{2(g)}, 1\,bar | H^+_{(aq)} 1\,M | AgCl_{(aq)} 1\,M | Ag_{(s)}$
$Zn(s) + C{u^{2 + }}(0.1\,M) \to Z{n^{2 + }}(1\,M) + Cu(s)$
$E _{ Zn ^{2}+\mid Zn }^{ o }=-0.76 V$
