{\begin{aligned} \mathrm{n f \rightarrow 2} \\ \mathrm{ZnSO}_4 \end{aligned}}               {\begin{aligned} \mathrm{n f \rightarrow 1} \\ \mathrm{AgNO}_3 \end{aligned}}              {\begin{aligned} \mathrm{n f \rightarrow 2} \\ \mathrm{CuSO}_4 \end{aligned}}

\mathrm{ Q=n \times n f \times F \\ }

\mathrm{ I \times t=\frac{108 \mathrm{~g}}{108 \mathrm{~g}} \times 1 \times \mathrm{F} \\ }

\mathrm{ t=482.5 }
