46. A student wants to deposit 10.0 g of gold onto a ring from a solution of AuCl 3. How long (in hours) must the student run a 0.750 A current to deposit the desired mass of Au? 47. Calculate the current required to plate out 25.0g of nickel from an aqueous solution of NiSO4 if the current runs for 6.00 hr. 48. An electroplating firm wishes to plate 14.5 g of Cu onto a pair of baby shoes from a Cu(NO3)2 solution. If a 2.45 A current is used, calculate the time required in hours. 49. In a certain electrolysis experiment, 1.44 g of Ag were deposited in one cell (containing an aqueous AgNO3 solution), while 0.120 g of an unknown metal X was deposited in another cell (containing an aqueous XCl3 solution) in series with the AgNO3 cell. Calculate the molar mass of X.
