Question

Calculate the amount of charge on 180 g of water

Answer 1

180gms= 10 moles

Each water molecule has 10 electrons. (8 from the oxygen, one from each hydrogen). 1 mole of electrons has a charge of around 96,500 Coulombs. This is referred to as Faraday’s constant. Therefore, 10 moles of electrons would have a total charge of 965,000 Coulombs, although water has a net charge of 0, since there is one proton to cancel out the charge of each electron.
