For Questions 1 to 4: Giorno Giovanna likes golden stuff. However, since he is currently broke, he has to settle for objects with gold plating. He decided to deposit 55.00 g of gold over an iron medallion by electroplating it from a solution containing Au3* ions while utilizing a constant current of 2.225 A. (MM of gold= 196.97 g/mol) How many electrons does each gold ion need in order to be reduced to its metallic state? 2 B 3. 4.
