A 175-g sample of water is saturated with KNO3 at 40ºC. What mass of KNO3 forms a precipitate if the solution is cooled to the freezing point of water? (Refer to the Solubility and Temperature graph.)

Answer 1

Marie, I'll let you in on a little secret. There aren't many people who have the millions of solubility graphs/tables memorized. If you can read the table/graph and post that with your question, someone here will be able to help.
