A copper, Cu(s), electrode is immersed in a solution that is 1.00 M in ammonia, NH3, and 1.00 M in tetraamminecopper(II), [Cu(NH3)4]^{2+}. If a standard hydrogen electrode is used as the cathode, the cell potential, Ecell, is found to be 0.085 V at 298 K.
Half reaction of Cu = .337 V
Half reaction of H = .000 V
Based on the cell potential, what is the concentration of Cu^{2+} in this solution?
