Ksp = [Ba^2+] [F^-]^2
Ksp = [x] [2x]^2 = (x)(4x^2) = 4x^3
1.0x10^-6 = 4x^3 => x^3 = 1.0 x 10^-6 / 4 = 2.5 x 10^-7
x = 3?2.5 x 10^-7 = 0.0063M
M = mol/L
0.0063 mol / L (208.23 g / 1 mol) = 1.31 g/L

Thanks for your feedback!

Ksp of barium fluoride, BaF2 is 1.0 x 10^-6. Calculate its solubility in grams per liter, knowing that BaF2 has a molar mass of 208.23 g/mol: BaF2 (s) ⇌ Ba^2+ (aq) + 2F^- (aq) Ksp = [Ba^2+][F^-]^2 1.0 x 10^-6 = (x)(2x)^2 1.0 x 10^-6 = 4x^3 x^3 = 2.5 x 10^-7 x = (2.5 x 10^-7)^(1/3) x ≈ 6.3 x 10^-3 g/L
