The overall formation constant for Cu(NH3)42+ is 1.1x1013 at 25oC. What is [Cu2+], in moles per litre, at equilibrium when 8.3 g Cu(NO3)2 is dissolved in 0.500 L of 1.00 mol/L NH3(aq)? Assume that there is no volume change when the Cu(NO3)2 is added to the solution. Give your answer accurate to two signficant figures. Enter 1.23x10-10 as 1.23e-10. Give your answer in mol/L Molar masses (in g/mol) N, 14.01 O, 16.00 Cu, 63.55 Hint: Assume that Cu2++4NH3 --> Cu(NH3)42+ is the only important reaction. Notice that the equilibrium constant for this reaction is very large.
