Explanation / Answer

solubility of Sr3(AsO4)2 = 0.0670 g/ L

molar solubility = 0.0670 / 540.7 = 1.239 x 10^-4 M

Sr3(AsO4)2   ----------------> 3 Sr+2 + 2 AsO43-

                                                 3 S             2S

Ksp = [Sr+2]^3[AsO43-]^2

       = (3S)^3 (2S)^2

      = 108 S^5

      = 108 x (1.239 x 10^-4)^5

Ksp = 3.15 x 10^-18
