A penny weighs 2.50 g and it is made of an inner part of Zn and a coat of Cu that is added using electroplating. If a 1.00L solution with a [Cu2+] = 4.95M is used to electroplate Cu, what is the concentration of the solution after it has been electrolyzed for 17.18h under a current of 2.09A? The half-cell equation is: Cu2+ + 2e- -> Cu and E° =+0.34V
