$Pt/ M/M^{3+}(0.001 \,mol\, L^{ -1})/Ag^+(0.01\, mol\, L^{-1})/Ag$
The emf of the cell is found to be $0.421\, volt$ at $298\, K$. The standard potential of half reaction $M^{3+} + 3e \to M$ at $298\, K$ will be .............. $\mathrm{volt}$
(Given $E_{A{g^ + }/Ag}^o $ at $298\, K\, = 0.80\, Volt$ )
