- Jack measured the mass of an empty evaporating dish and watch glass, and weighed approximately 0.5 g of an unknown solid into the evaporating dish. He then followed the procedure for Lab Exercise 5, and collected the rest of the data in the table below. Please note that row letters correspond to those found on the data sheet that you will use in lab. You will need to refer to this data to answer Questions 13 through 20: A Mass of empty evaporating dish + watch glass 65.362 g B Mass of dish + watch glass + initial solid 65.864 g C Mass of dish + watch glass + carbonate 65.705 g D Mass of dish + watch glass + chloride 65.716 g What was the mass (in grams) of the unknown solid that Jack used in his experiment. Type the numerical answer only in the box below (no units!). Report your answer to the correct number of significant figures.Why is paper used for weighing dry, non-hygroscopic chemicals only?
