What is the solubility of silver chloride in water at 25C? (Ksp = 1.6 x 10^-10)

I don't know how to do the work

AgCl(s) ==> Ag^+ + Cl^-

Let x = molar solutility of AgCl.

Then x = molar concentration of Ag^+.

and x = molar concentraton of Cl^-

Then Ksp = (Ag^+)(Cl^-) = 1.6E-10

Substitute from above.

x*x=1.6E-10

Solve for x. That is molar solubility in mols/L. If you want grams AgCl, then M x molar mass = grams.
