At anode $2 \mathrm{OH}^{-} \rightarrow \mathrm{H}_{2} \mathrm{O}+\frac{1}{2} \mathrm{O}_{2}+2 \mathrm{e}^{-}$
$E_{A g}=\frac{108}{1}$ ; $E_{O_{2}}=\frac{\frac{1}{2} \times 32}{2}=8$
$\frac{{{\text{W}}_{\text{Ag}}}}{{{\text{E}}_{\text{Ag}}}}=\frac{{{\text{W}}_{{{\text{O}}_{2}}}}}{{{\text{E}}_{{{\text{O}}_{2}}}}}\Rightarrow $ ${{\text{W}}_{\text{Ag}}}=\frac{1.6\times 108}{8}=21.6\,\text{gm}$
