Releasing 1 mol of oxygen, O 2, involves 4 mol of electrons. Now put the numbers in. Four moles of electrons is 4 faradays. 4 x 96500 coulombs give 24 dm 3 O 2 at rtp. So, if 4 x 96500 coulombs give 24 dm 3 O 2, work out what volume of oxygen would be produced by 900 coulombs. Volume of oxygen = 900/(4 x 96500) x 24 dm 3 = 0.056 dm 3
