Hello, I am working on a ElectroChem problem dealing with ΔG and E°Cell

The equation that relates the two as I'm sure you all know is ΔG=-nfE°cell

I have already found ΔG which is at 18KJ now figuring out E°cell should be easy and it would be but the equation gives no convenient specification of electron moles exchanged and as we all know F is the Faraday's Constant of 9.65x10^4 (rounded to 2 sigfigs)

For the equation below what is the electron molar exchange (its not 1 I already tried that) thank you

FeO (s) + H₂(g)  Fe(s) + H₂O(L)

Thank you and I hope Im just doing something stupid and its an easy fix

What are the charges of each atom on each side of the equation?

Right?!! Thats what I was wondering too. That is the equation. There is nothing else specified. No charges or anything. I figured there is no electron exchange. I tried zeroing everything out but I got a no go.

How does the oxidation numer for iron change? Either I don't understand the problem or it is painfully trivial.
