See lab write-up for example. Use attached grid (See Next Page). Provide a Title to the plot and to each axis. Be consistent in foumbering the axes! (HINT: See Lab Writeup for Example Graph.) Use your graph to answer the following questions. Questions: 3. Lary to Place po 1. Use your graph to answer the question: How many grams of KNO, can be dissolved in 100 but mL of H20 at the following temperatures? (Give an explanation for each answer.) Yevents Vike When prop trifuge a. 30C b. 60C c. 70C 2. Define the terms: saturated, unsaturated, and supersaturated. 3. Use your graph to answer the question: Classify the following KNO, solutions as saturated, unsaturated or supersaturated. Explaining your answer. a. 75 g KNO/100 mL H20 at 40C b. 60 g KNO3 /100 mL H20 at 50C 4. In step 9 you were cautioned against holding the test tube in the ice bath, as this will result in large amounts of KNO, crystallizing, which will not yield a valid data point. If this happened, would the solution be unsaturated, saturated, or supersaturated? Explain. 5. What is the lowest temperature at which a solubility measurement could be performed
