Questions 1. Discuss the difference between the experimental and theoretical molar mass values of the "unknown". Speculate on what might have caused any difference. In Part III, suppose you weighed the empty test tube/flask first, then weighed the test tube/flask + cyclohexane, but forgot to weigh the solution once the "unknown" was added. To rectify this mistake, you weigh the "unknown" solution after the experiment is performed. The only problem is that you forgot to wipe off the water droplets from the outside of the test tube! How would this affect your calculated value for the molar mass of the "unknown"? Explain.
