The conductivity of a saturated solution

The conductivity of a saturated solution of a sparingly soluble salt MIX in water at 298 K is 1.887 × 10 -4 S m -1 . The molar conductivity of MX at infinite dilution at this temperature is 138.3 × 10 -4 S m 2 mol -1 . Calculate The solubility and solubility product of MX at this temperature.
