### how to get n in equation

i don’t understand how to find the n in this equation. where do you look in the given equation to find n?

You look at how many electrons are being transferred!

I am not sure which equation you are referring to. If you are asking about the "n" in the nernst equation, then we calculate it based of the # of electrons from the two half reactions once they are balanced. Since the electrons will be the same in the two half reactions in order for it to cancel, we take the "n" as the number of electrons.

Look at the balanced half reactions and determine how many electrons are being transferred in the redox reaction.

N refers to the number of electrons being transferred.

N is found by finding how many electrons are being transferred in the process.
