The formation constant of a complex ion [M(NH3)4]2+(aq) is 8.8E8. If a solution is prepared by adding 0.4 mol of [M(NH3)4]Cl2 to 525.0 mL of water, what is the equilibrium concentration of free M2+(aq) ions? Include 3 significant figures

Consider the insoluble compound silver hydroxide , AgOH . The silver ion also forms a complex with cyanide ions . Write a balanced net ionic equation to show why the solubility of AgOH (s) increases in the presence of cyanide ions and calculate the equilibrium constant for this reaction.For Ag(CN)2- , Kf = 5.6×1018 . Be sure to specify states such as (aq) or (s).   Net Equation= _________ K = ________
