2.5 gm of CuSO4 are dissolved in 9.0 x 10 to the second ml of 0.30 Molar NH3. What are the concentrations of Cu+2, NH3, and Cu(NH3)4 at equilibrium?

The molar concentration of 2.44 grams of CuSO4 in 900 ml solution is

CuSO4 (s)  Cu2+ (aq) + SO42- (aq)
0.0174 0.017 4 0.0174

Cu2+ (aq) + 4NH3 (aq)  Cu(NH3)42+
