What is the equilibrium concentration of

What is the equilibrium concentration of Cd2 ions when cadmium oxalate Cd(ox) is dissolved in water to make an initial concentration of 0.0100 M? All of the cadmium oxalate dissolves but only a fraction of it dissociates as indicated below. What are the equilibrium concentrations of the 3 species shown in the reaction equation below?Cd(ox)=(Cd2 ) (ox2–)K = 2.0 × 10–4
