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 0.630 A is passed through an electroplating cell with an aqueous solution of Ag₂SO4 in the cathode compartment for 28.0 seconds. Calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. Round your answer to 3 significant digits.
