1. Summarize the steps performed when using an analytical balance. 2. How could you distinguish a problem with a balance from a user technique issue using the collected statistics? 3. Matt weighed a crucible three times and calculated a mean mass of 12.3453 g with a standard deviation of 0.0002 g, while Sunil's result for the same crucible was 12.3448 g with a standard deviation of 0.0003 g. Do their results agree? Why or why not? 4. Next week, you will use the dried NaCl to create a solution. Why is it beneficial to dry any hydroscopic solid prior to weighing out the solid to make a solution? 5. If you wanted to accurately prepare 500 mL of a 1.500 M solution of NaCl, how would you do this? Include the mass of NaCl needed as well as all tools used in preparing this solution.
