Chapter 17, Problem 70P

the electroplating of a silver spoon, the spoon acts as thecathode and a piece of pure silver as the anode. Both dipinto a solution of silver cyanide (AgCN). Suppose that acurrent of 1.5 A is passed through such a cell for 22 minutesand that the spoon has a surface area of $16{\text{cm}}^2.$ Calculatethe average thickness of the silver layer deposited onthe spoon, taking the density of silver to be $10.5\text{g}{\text{cm}}^{-3}.$
