The diagram shows an electrochemical cell involving two metal / metal ion system. 

The standard electrode potentials for the half-cells are:

${\mathrm{Ag}}^{+}+{\mathrm{e}}^{-}\stackrel{ }{\rightleftharpoons }\mathrm{Ag}: {\mathrm{E}}^{°}=+0.80 \mathrm{V}$

${\mathrm{Cu}}^{2+}+2{\mathrm{e}}^{-}\stackrel{ }{\rightleftharpoons }\mathrm{Cu}: {\mathrm{E}}^{°}=+0.34 \mathrm{V}$

Calculate a value for the cell voltage. Show your working.
