Two saturated aqueous solutions are prepared at 25 ºC. Solution 1 is made by dissolving cadmium fluoride (CdF2 Ksp =6.44×10 −3 ) in 100.0 mL of water until excess solid is present. Solution 2 is prepared by dissolving lithium fluoride (LiF, Ksp= 1.84 x 10 −3 ) in 200.0 mL of water until excess solid is present. Which solution has a higher fluoride ion concentration?

what is the molar concentration of F-1 in the CdF2 solution?

what is the molar concentration of F-1 in the LiF solution?
