For a science experiment you need to electroplate a 150nm-thick zinc coating onto both sides of a very thin, 1.0cm * 1.0cm copper sheet. You know that the charge carriers in the ionic solution are divalent (charge 2e) zinc ions. The density of zinc is 7140kg/m^3.
If the electroplating apparatus operates at 1.9 mA, how long will it take the zinc to reach the desired thickness?
