All the energy released from the reaction XY, ΔrGo=-193 kJ mol-1 is used for oxidizing M+ as M+M3++2e- , Eo= -0.25 V
Under standard conditions, the number of moles of M+ oxidized when one mole of X is converted to Y is
[F=96500 C mol-1]

Solution

M+M3++2e-
Go=-nFEo for 1 mole of M+
Go=-2×96500×-0.25J
=+48250 J/mole
=48.25 KJ /mole
Energy released by conversion of 1 mole of
XY
G=-193 KJ
Hence mole of M+ convert
19348.25=4
