90.0g of magnesium chloride was placedin 50.0cm³water to give a saturated solution at 298k If the solubility of thesalt is 8.0mol/dm³ at the same temperature, what is the mass of thesalt less dissolved at that given temperature [mg=24,Cl=35.5]

The mass of the salt less dissolved at 298K is 24.0 mg of magnesium and 35.5 mg of chlorine.
