Question

Estimate the solubility of calcium fluoride, CaF2+, (a) in moles per liter and (b) in grams per liter of pure water.
CaF2+(s) = Ca2+(aq)+2f-(aq)
I have corrected the equation you wrote.
.......CaF2(s) = Ca2+(aq)+2F-(aq)
I......solid.....0.........0
C......solid.....x.........2x
E......solid.....x.........2x

Substitute the E line into the Ksp expression and solve for x = solubility in mols/L.
grams = mols in 1 L x molar mass
