Density Quiz Review (7th)

Select ALL that are true of density

• Density is a measure of how much mass there is in a certain space (volume)

• Density is a measure of how close together or far apart the molecules are

• Density is a measure of how heavy an object is - it DOESN'T have anything to do with the space or volume of an object

• Density is a measure of how big an object is - it DOESN'T have anything to do with how much mass the object has.

What is the formula for density?

• mass / volume

• volume / mass

• mass x volume

• volume - mass

Mykhi wants to find the density of his computer mouse. He puts it on a scale and sees that it's mass is 4g. Then, he dunks it in 5mL of water, which rises to 7mL.

Write what EQUATION you would use to solve this problem (example: "5/7"). Do NOT include the answer - just your work!

Elijah wants to find the density of his agenda. First, he puts it on a scale and finds that the mass is 20g. Then, he dunks it in 10mL of water. The water rises to 12mL. What is the density of the agenda?
*Remember: $density\ =\ mass\ \div volume$
*In the box below, just type your answer (NO g/mL units necessary)

Courtney wants to find the density of a deflated basketball. He puts it on a scale and sees its mass is 6g. Then, he dunks it in 10mL of water. The water rises to 13mL. What is the density of the deflated basketball?

*Remember: $density\ =\ mass\ \div volume$
*Just type your answer below (example: "7").
