Chemistry Thermodynamics help?



How can I calculate Ksp? All I have is KNO3 was dissolved in water and heated until the crystals dissolved. Then the solution was removed from heat and allowed to reform- the temperature they reformed at was measured which was called "T of Dissolution". Then the test tube was heated again and the temperature at which the crystals reappeared was called "T of first crystals". These trials were repeated with varying mass of KNO3. Also- how to find molarity of KNO3?
