The cell potential for \(\mathrm{Zn}\left|\mathrm{Zn}^{2+}(\mathrm{aq})\right|\left|\mathrm{Sn}^{x+}\right| \mathrm{Sn}\) is \(0.801 \mathrm{~V}\) at \(298 \mathrm{~K}\). The reaction quotient for the above reaction is \(10^{-2}\). The number of electrons involved in the given electrochemical cell reaction is ____________.


\(\left(\right.\) Given \(: \mathrm{E}_{\mathrm{Zn}^{2+} \mid \mathrm{Zn}}^{\mathrm{o}}=-0.763 \mathrm{~V}, \mathrm{E}_{\mathrm{Sn}^{x+} \mid \mathrm{Sn}}^{\mathrm{o}}=+0.008 \mathrm{~V}\) and \(\left.\frac{2.303 \mathrm{RT}}{\mathrm{F}}=0.06 \mathrm{~V}\right)\)
