Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of is passed through an electroplating cell with an aqueous solution of in the cathode compartment for seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to significant digits. also, be sure your answer contains a unit symbol.
