In the presence of of nh3 cu2 forms the complex ion cunh342

Question

In the presence of of NH3, Cu^2+ forms the complex ion Cu(NH3)4^2+. Explain if the equilibrium concentrations of Cu^2+ and Cu(NH3)4^2+ are 1.8x10^-17M and 1.0x10^-3M, respectively, in a 1.5M NH3 solution, Compute the value for the overall constant of Cu(NH3)4^2+ Cu^2+(aq) + 4NH3 (aq) <=> Cu(NH3)4^2+(aq) Koverall =?
