From Faraday's first law of electrolysis, the weight of a chemical substance deposited at an electrode is directly proportional to the quantity of electricity passed through the electrolyte.
Q = current (c) in amperes × time (t) in seconds
= 23*1*60*60 = 82800 coulombs
96500 coulombs of charge = 1 faraday
82800 coulombs of charge = 0.8580 faraday
Again, 3 F of electricity produces 27 grams of Aluminium
Therefoe, 0.08580 F of electricity produces (27*0.8580/3) = 7.7 grams of Aluminium
