Question 1

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)
◦ 9.1 mA
◦ 1800 mA
◦ 540 mA
◦ 33 A

Question 2

The resistivity of gold is at a temperature of 20°C. A gold wire that is 0.50 mm in diameter and 44 cm long carries a current of 380 mA. How many electrons each second pass a given cross section of the wire at 20°C? (e = 1.60 × 10-19 C)
◦ 6.3 × 1015
◦ 2.8 × 1014
◦ 2.4 × 1018
◦ 2.4 × 1017
◦ 1.2 × 1022
