A solution containing trace iridium as the IrCl63āˆ’ ion, is processed at an appropriate potential. Assume the iridium is not depleted during the plating. Calculate the maximum mass of Ir recovered if average deposition current is 3.6 x 10āˆ’4 A for 74.0 min? Report your answer in units of mg and show 3 significant digits, standard notation (not scientific)
