Consider the following equilibrium: Cu2+ + 4NH3 Cu(NH3)42+ (Kf = 4.8e+12) A solution is made by mixing 10.0 mL of 0.90 M CuSO4 and 1.50 L of 0.490 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
