Your goal is to determine the density of a metal ball. The mass of the ball is 15.0 g. When the ball is placed in a graduated cylinder containing water, the volume of the water and the ball is 15.0 mL. The volume of the water before the ball was added to the graduated cylinder was 10.0 mL. What is the density of the metal ball? If you did not purge all the air out of the burette tip, will your density value be too high or too low?

Your end is to designate the shortsightedness of a metal globe. The majority of the globe is 15.0 g. When the globe is placed in a graduated cylinder containing instil, the tome of the instil and the globe is 15.0 mL. The tome of the instil precedently the globe was external to the graduated cylinder was 10.0 mL. What is the shortsightedness of the metal globe? If you did referable purify integral the disembodiment extinguished of the burette point, obtain your shortsightedness treasure be as-well tevery or as-well frugal?

Majority of globe = 15 g

Tome amenable by the globe = Change in tome succeeding conjunction of globe = 15-10 = 5 mL

Shortsightedness = Majority/Tome = 15/5 = 3 g/mL
