How long will it take the zinc to reach desired thickness

Reference no: EM13502269

For a science experiment you need to electroplate a 120nm-thick zinc coating onto both sides of a very thin, 2.5cm X 2.5cm copper sheet. You know that the charge carriers in the ionic solution are divalent (charge 2e) zinc ions. The density of zinc is 7140 kg/m^3.

If the electroplating apparatus operates at 1.7mA, how long will it take the zinc to reach the desired thickness?

t=____ (in seconds)
