Chapter 22, Problem 45(choose chapter or problem)
For a science experiment you need to electroplate a I 00-nmthick zinc coating onto both sides of a very thin, 2.0 cm X 2.0 cmcopper sheet. You know that the charge carriers in the ionicsolution are divalent (charge 2e) zinc ions. The density of zinc is7 140 kg/m3. Tf the electroplating apparatus operates at 1.0 mA,how long wi ll it take the zinc to reach the desired thickness?
