### Homework 14.9

When solving for this problem how do you find n? Are you supposed to calculate it based on individual oxidation numbers or from the overall charges on either sides of the equations?

### Re: Homework 14.9

In order to use the formula $\Delta G_{r}^{\circ} = -nFE^{\circ}$, you can solve for n by writing out the oxidation and reduction half reactions and balancing them.
