The question: Find the Ksp of Silver Acetate.

It is based on a lab conducted where copper metal is made to react with 0.1L silver acetate solution (saturated).
The 2 relavent equations are: Cu + 2Ag⁺--> Cu²⁺ + 2Ag and
C₂H₃O₂Ag <=> C₂H₃O₂^- + Ag⁺

The mols of Cu reacted was given (9.44 x 10^-4)and I used that to find concentration of Ag⁺ using the first equation, equivalent mol ratios and the formula c=n/v (v=0.1L). I got 0.0189 M.

****I realize Ksp = [Ag⁺][C2H3O2^-] but how do I find molar [C2H3O2]!?

Its the same:

From your equation : C2H3O2Ag <=> C2H3O2- + Ag+

We see that [Ag+] and [C2H3O2-] are equivalent at equilibrium, since it is one to one molar ratio.

So in your case (if your value of [Ag+] is correct), Ksp = 0.0189^2, Ksp=3.57*10^-4.
