The typical battery used in a standard flashlight produced approximately 1.5 V. If the value for ΔG° of the reaction were −289,500 J, what would you calculate as the moles of electrons exchanged in the balanced redox reaction?

I got 1 mols for this...but i think it's wrong, can explain what am I suppose to do?

• chemistry -

DGo = -nEF
-289,500 = -n(1.5)(96,485)
n = ?

okay I ended up getting 2 instead of one? XD I made a mistake in my half reactions...thanks!
