Thank you for the opportunity to help you with your question!

Substitute into the Ksp expression: Ksp=[Pb2+][Cl-]^2, Ksp=(s)(2s)^2

Substitute the value of Ksp into the equation and solve for s: Ksp=4S^3, S=cubic root of (Ksp/4)=cubic root of (1.17*10^-5  / 4)

S=1.43*10^-2 M

Please let me know if you need any clarification. I'm always happy to answer your questions.
