Olympic gold medals are not purely gold, but only plated with gold. An Olympic gold medal must contain a minimum of 6 grams of gold (MW = 196.97 g mol) and at least 92.5% silver. In the 2021 Tokyo Olympics, a total of 340 gold medals were awarded to deserving athletes. Suppose each medal is made by coating a 60-mm diameter, 3-mm thick, gold-free silver alloy disk with gold via electrolytic deposition using gold (III) solution. a) Calculate the time required( in hrs.) to finish plating all the gold medals used in the Tokyo Olympics with minimum gold content if the available electricity source can deliver 50 A of current.
