Consider the following equilibrium: Cu2+ + 4NH3 Cu(NH3)42+ (Kf = 4.8e+12)

A solution is made by mixing 10.0 mL of 1.20 M CuSO4 and 1.30 L of 0.250 M NH3. Assume additive volumes to answer the following questions. Give all answers to three sig figs.

a) What is the concentration of NH3 in the resulting solution?

[NH3] = M

b) What is the concentration of Cu(NH3)42+ in the resulting solution?

[Cu(NH3)42+] = M

c) What is the concentration of Cu2+ in the resulting solution?

[Cu2+] = M
