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. One way to approach the problem is to imagine the reaction proceeds to equilibrium by first going 100% to completion and then backing up a little..
