Measuring mass 1. Find the actual weight of the items in the table below and record. Some hints on measuring Hint-Use the triple beam balance for smaller items, and the floor scale for larger ones. Ask your instructor for help using either of these. Hint - Your instructor will tell you about the weight of an automobile later.

1.65 An industrial engineer is designing a process to manufacture bullets. The mass of each bullet must be within 0.2 5% of 150 grains. What range of bullet masses, in mg, will meet this tolerance? 1 grain = 64.79891 mg.
1.18 Two golfers are practicing shots around a putting green. Each golfer takes 20 shots. Golfer 1 has 7 shots within 1 meter of the hole, and the other 13 shots are scattered around the green. Golfer 2 has 17 shots that go into a small sand trap near the green and 3 just on the green near the trap. Which golfer is more precise? Which is more accurate?
Visit this PhET density simulation (http://openstaxcollege.org/l/16phetmasvolden) and select Custom Blocks and then My Block. Enter mass and volume values for the block such that the mass in kg is less than the volume in L. What does the block do? Why? Is this always the case when mass volume How would (a) and (b) be different if the liquid in the tank were ethanol instead of water How would (a) and (b) be different if the liquid in the tank were mercury instead of water

1. A student weighs an empty special round bottom flask and stopper. He finds the mass to be 56.972 g. He then adds about 5 mL of an unknown liquid and heats the flask in a boiling water bath at 100°C. He allows all the liquid to vaporized and then removes the flask from the bath, stoppers it, and lets it cool. Upon cooling, he briefly removes the stopper, then replaces it and weighs the flask and condensed vapor, obtaining a mass of 57.917 g. The volume of the flask is known to be 240.2 mL. The barometric pressure in the laboratory that day is 743 mm Hg. What was the pressure of the vapor in the flask in atm? O 0.9776 atm 0.98 atm 0.978 atm 0.977 atm
