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.

solve as neatly as possible and show completesolution. Round your final answer to 4 decimal places and box / highlight all final answers. and all values must include proper units with proper conversion if needed in your solution. kindly folllow the format Given,Required,Solution subject physical chemistry #4) final answer must be in cm/sec 4. An iron sphere of density 7.874 g/cm3 is falling at a steady speed in glycerol at 200C. The density of glycerol is 1.2613 g/ml and its viscosity at this temperature is 1.49 kg/m-s. If the diameter of the sphere is 10 mm, find the speed (in cm/s), assuming Stoke’s Law is valid.
