Water was added to 120g of salt, MCl2 to produce 60.0cm3 of a saturated solution at 45o C. Its solubility at 45o C is 8.0 mol dm-3. i) Calculate the mass of the salt which remain undissolved.
ii) Is the solution saturated or unsaturated or supersaturated? Give reason for your answer. (M = 24 , Cl = 35.5)
