DENSITY

DENSITY is a characteristic property because it is a specific aspect of a substance. Whether we have a lot of the substance, or a little, the density will never change.

A rock with a mass of 4. 53 g is dropped into a graduated cylinder A rock with a mass of 4.53 g is dropped into a graduated cylinder. The water level rises from 10 mL to 11.5 mL. What is the density of the rock?

Vinegar has a density of 1. 05 g/mL. How much volume does 24 Vinegar has a density of 1.05 g/mL. How much volume does 24.15 g of vinegar take up?

Molasses has a density of 1. 4 g/mL Molasses has a density of 1.4 g/mL. What is the mass of molasses in a container that is holding 50 000 mL of molasses?

Give a brief definition of mass.   Give a brief definition of volume. Give a brief definition of density and show the formula for calculating density.

Aluminum is used to make airplanes, while cast iron is used to make weightlifting equipment. Explain why the densities of these metals make them useful for these purposes.   Explain in detail how you would find the density of a rock. Zoe measures the mass of an 8 cm3 block of sugar to be 12.9 g. What is the density of the sugar?

Max fills a 50 mL container with 43. 5 g of cooking oil Max fills a 50 mL container with 43.5 g of cooking oil. What is the density of the oil? Hayley records the mass of an aluminum cube as 176 g. If one side of the cube measures 4 cm, what is the density of the aluminum? Jennifer drops a piece of cork into water and finds that it displaces 23.5 mL of water. The piece of cork has a mass of 5.7 g. What is the density of the cork?

A piece of wood that measures 2 cm by 3 cm by 4 cm has a density 2 g/cm3. What is the mass of the wood? Refer to the piece of wood in the previous question. Based on the density you calculated, would it float in water? The density of water is 1 g/cm3.

Georgia is about to carve a large rectangular block of granite, shown below. The block weighs 2700 g. What is the density of the granite? A piece of PVC pipe displaces 60 mL when placed in a container of water. If the pipe has a mass of 78 g, what is the density?

A solid piece of magnesium has a mass of 1300 g and a density of 1 A solid piece of magnesium has a mass of 1300 g and a density of 1.75 g/cm3. What is the volume of the magnesium? A graduated cylinder has a mass of 50 g when empty. When 30 mL of water is added, the graduated cylinder has a mass of 120 g. If a rock is added to the graduated cylinder, the water level rises to 75 mL and the total mass is now 250 g. What is the density of the rock?

Cadence is performing an experiment with the following three fluids. Fluid A has a mass of 2060 g and a volume of 2000 mL. Fluid B has a mass of 672 g and a volume of 850 mL. Fluid C has a mass of 990 g and a volume of 1100 mL. If these fluids were to be poured into the same beaker, explain how each fluid would be layered, starting from the bottom and moving upward.

While digging in his backyard, Thomas finds an old coin with a mass of 26.7 g and a volume of 3 cm3. Emily finds a shiny object with a mass of 5.28 g and a volume of 2 cm3. Grace finds a ring with a mass of 107 g. She fills a graduated cylinder with 10 mL of water and puts the ring into the cylinder. The water rises up to the 15 mL mark. Manahil has a rectangular paperweight that measures 3 cm by 4 cm by 6 cm. It has a mass of 184.32 g.
