FeS ==> Fe^2+ + S^2-
Ksp = (Fe^2+)(S^=)
Look up the Ksp for FeS, set up an ICE chart, substitute into the Ksp expression and solve for the solubility.
Determine the solubility of FeS at 25 degrees Celsius

What is an ICE chart?
If we let x stand for the solubility of FeS, then x is the concn of iron(II) and x is the concn of S^2-.
................FeS ==> Fe^2+ + S^2-
initial...................0......0
change....................x.......x
equil.....................x.......x
I stands for initial
C stands for change
E stands for equilibrium.
I have set one up above for you.
So you substitute x for (Fe^2+) and x for (S^2-), and whatever you find in your text for Ksp FeS, and solve for x.
