100g of water at 50C. The solution is rams of KNO3, will precipitate? Use the graph below to answer the following questions: a) At 10C, a saturated solution of KNO3 contains 20 grams of solute in 100ml of water. How many grams of KNO3 must be added to saturate the solution at 50C ? b) How many grams of potassium chlorate, KCl, must be added to 400mL of water to produce a saturated solution at 80C ? c) What is the smallest volume of water, in mL, required to completely dissolve 60 grams of NaNO3 at 10C ? e) A sample of potassium nitrate, KNO2,(50.0g) is dissolved in 100g of water at 50C. The solution is cooled to 20.0C and some precipitate is observed. How many grams of KNO3, will precipitate
