The cell potential for $\mathrm{Zn}\left|\mathrm{Zn}^{2+}(a q) \| \mathrm{Sn}^{\mathrm{X}+}\right| \mathrm{Sn}$ is 0.801 V at 298 K . The reaction quotient for the above reaction is $10^{-2}$. The number of electrons involved in the given electrochemical cell reaction is. $\_\_\_\_$ (Given $\mathrm{E}_{\mathrm{Zn}^2+\mid \mathrm{Zn}}^0=-0.763 \mathrm{~V}, \mathrm{E}_{\mathrm{Sn}^{x+1} \mid \mathrm{Sn}}^0=+0.008 \mathrm{~V}$ and $\frac{2.303 \mathrm{RT}}{\mathrm{F}}=0.06 \mathrm{~V}$ )
