For AgCl, at 25°C, K°sp =1.60×10-10.

For KNO3 solutions:
μ   0.050           0.100           0.150           0.200
γAg+   0.8105   0.7565   0.7199   0.6914
γCl-   0.8217   0.7776   0.7503   0.7306

Determine the molar solubility of silver chloride in 0.150-M potassium nitrate solution.
Report your answer to 3 significant figures.

I dont understand where to start for this qn
Are there any formulas i could use for this qn??

You are already given activity coefficients.

would i have to find the concentration of the Ag⁺ ions and the Cl^- ions first and would the concentrations of both ions be the same?
and how is the concentration of potassium nitrate relevant?
