Question

Impure copper containing Fe, Au, Ag as impurities is
electrolytically refined. A current of 140 A for 482.5 s
decreased the mass of the anode by 22.26 g and increased
the mass of cathode by 22.011 g. Percentage of iron in
impure copper is
[Given molar mass of Fe = 55.5 g mol-1, molar mass
of Cu = 63.54 g mol-1]​
