All the energy released from the reactionXY,ΔrGo=-193 kJ mol-1is used for oxidizingM+asM+M3++2e-,Eo=-0.25V.
Under standard conditions, the number of moles ofM+oxidized when one mole of X is converted to Y is [F = 96500 Cmol-1]

Answer:
4.00
Solution:

ΔGo=-nFEo

-n=193×10396500×0.25=8

So No. of moles ofM+oxidized by 1 moles ofX=82=4
