So it's 96,500. And what it basically tells us is it's the amount of charge that exists on 1 mol of electrons as they move move along that particular cell membrane. Now, Z, what Z is it's basically the value of the charge on that particular ion. So if the charge, let's say we're dealing with sodium ions, the Z value is plus one. If we're dealing with chloride ions, the Z value is negative one. If we're dealing with, let's say potassium has a positive one, it's also positive one, and so forth.
