2Ag⁺ + 2I^- --> I₂ + 2Ag

Is the number of mole electrons one or two?
I think it's only one but I'm not sure.

Write half reaction for iodine.

I^- --> I₂

Now balance the number of atoms and charge

2I^- --> I₂ + 2e

Note that amount of iodine present in the half reaction is exactly the same as in the final balanced reaction.

Do you see now number of moles of electrons?

So, 2 mole of electrons?

Thank you very much!
