A jeweler needs to electroplate gold,having an atomic mass of 196.97 g/mol,onto a bracelet.He knows that the charge carriers in the ionic solution are singly-ionized gold ions,Au+,and has calculated that he must deposit 
Of gold to reach the necessary thickness.How much current does he need to plate the bracelet in 3.0 hours? (e = 1.60 × 10-19 C,NA = 6.02 × 1023 atoms/mol)
A) 9.1 mA
B) 540 mA
