in the presence of NH3, Cu+2 forms the complex ion [Cu(NH3)4]+2. If the equilibrium concentrations of Cu+2 and [Cu(NH3)4]+2 are 1.8x10^-17M and 1.0x10^-3M respectively, in a 1.5 M NH3 solution, calculate the value for the overall formation constant of [Cu(NH3)4]+2.

Cu+2(aq)+ 4NH3(aq)-> [Cu(NH3)4]+2(aq)
Koverall= ?
