How many electrons were transferred between an anode and cathode that produced 482.425 kilojoules of energy? All right, so here they want us to find electrons transferred, or in essence, moles of electrons transferred. We've seen this type of terminology when it comes to Faraday's constant, which is 96,485 coulombs per one mole of electrons.
We also know the conversion factor, that one Coulomb is equal to 1 Joule per 1 Volt. So we're going to start out here with 482.425 kilojoules. And what I'm going to do here is I'm going to say that one KJ is equal to 103 joules. Once I know joules now, we could cross multiply these two together so we can see that one Joule is equal to 1 coulomb times volts.
So that's conversion I can introduce here. We can say here that we have one Joule is equal to 1 coulomb times volts. And now, because we know this, we can say that Faraday's constant is 96,485 Coulombs per one mole of electrons. When I do that, that's going to give me 5 moles of electrons that are produced per Volt.
So here 5 moles of electrons would be involved in this transferring of this many kilojoules of energy.
