How Do You Solve a Chemical Equilibrium Problem Involving AuCl, NaCl, and H2O?

[Not a Wrench]

Homework Statement

Problem 132

Homework Equations

Not sure. I know we will use Kc=[Products]/[Reactants]

The Attempt at a Solution

I tried to devise a balanced equation to use: AuCl (s) + NaCl (s) + H2O (l) → Au+ + 2Cl- + Na+ and then try solving from there

That's not necessary. NaCl is completely dissociated, so you only need to consider the initial concentration of Cl^- in the solution.
