mols Mn(OH)2 = grams/molar mass = approx 3E-6 but this is an estimate. You should recalculate this and all that follows.

...........Mn(OH)2 ==> Mn^2 + 2OH^-
I..........solid........0.......0
C..........solid........x.......2x
E..........solid........x.......2x

Ksp = (Mn^2+)(OH^-)^2

Substitute this into Ksp expression and solve for Ksp.
