What is the mass?

In a saturated solution of the sparingly soluble salt AgIO_(3) (Mol. Mass = 283 g mol^(-1) ), the equilibrium which sets in is AgIO_(3)(s) iff Ag^(+)(aq)+IO_(3)^(-)(aq) . If the K_(sp) of AglO_(3) is 1 times 10^(-8)M^(2) at 298 K. What is the mass of AglO_(3) contained in 100 ml of its saturated solution at 298 K?
