According to Faraday's first Law of electrolysis mass of substance liberated is equal to

Easy
Solution

Mass of the substance deposited,decomposed,liberated at any electrode is directly proportional to the quantity of electricity passing through the electrolyte.

m \propto Q

m = eQ

m = eit

where e = electro chemical equivalent weight

             i = current in amperes

             t = time in sec for the flow of current
