Explanation / Answer

moles of AB2 = 0.0310 mol

concentration of AB2 = 0.0310 / 1 = 0.0310 M

AB2 (s)   --------------> A2+ (aq) + 2 B- (aq)

                                      S                2S

Ksp = [A2+][B-]^2

       = (S) (2S)^2

       = 4 S^3

        = 4 x (0.0310)^3

Ksp = 1.19 x 10^-4
