In tin plating a continuous steel strip 0.25 m wide from an electrolyte (valence charge: 2) contained in a 5 m long tank, the speed of the strip is 5 m/sec, and the electrode efficiency is 100%.

(a) Find the thickness of the coating deposited on each face of the strip if a current density of 3,000 A.m-2 is used (given: density of tin = 7.31 g/cc, atomic weight of tin = 118.7).

(b) What would be the coating thickness if only one side of the strip received the coating (the other side being masked with a non-conducting tape)? To answer part (b), either show calculations or provide reasoning.
