I need help filling out the table for Part C and drawing 2 cooling curves 1. for hexane data 2. for naphthelene and hexane data. please!!

Part C: Determining the K, for Cyclohexane Chemicals Used Materials Used Naphthalene ( CH) Cooling curve apparatus (from Part B) NaCl Spatula Ice Analytical balance Stopwatch Half the class, working in pairs Measure approximately 0.30 grams of naphthalene (record the actual mass used) and transfer into the test tube filled with cyclohexane that you used in Part B. Make sure the naphthalene is completely dissolved before proceeding to the next section. Add ice and salt to the 400-ml beaker as needed. Determine the freezing point of the solution in the same way you did for the pure solvent. Again, be sure to collect data for at least 10 minutes. Dispose of the cyclohexane solution according to your instructor's directions.
