a graduated cylinder has a mass of 80g when empty. When 20 mL of water is added, the graduated cylinder has a mass of 100g, IF a stone is added to the graduated cylinder, the water level rises to 45ml and the total mass is now 156g. What is the density of the stone?

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
