Density Credit Recovery

What two types of measurements make up DENSITY?

• Mass and Volume

• Temperature and Mass

• Grams and Centimeters

• Volume and Weight

Look at this image. Which object has the LOWEST density in water? How?

• The Ping Pong Ball because it floats to the top.

• The soda cap because it is not just full of air like the Ping Pong.

• The bolt because it has sunk to the bottom.

Jack has a rock. The rock has a mass of 14g and a volume of 2 cm3. What is the density of the rock?

• 7 mL

• 28 g/cm3

• 7 g/cm3

• 1/7 g/cm3

If an object has a density of 3.6 g/mL and you put it into water, will it sink or float?

• sink

• float

Frank has an eraser. It has a mass of 4g, and a volume of 2 cm3. What is its density?

• 8 g/cm3

• 1/2 g/cm3

• 2 g/cm3

• 24 g/cm3

What units are used to measure mass?

• g

• cm3

• g/cm3

• cm3/g

What is the formula for density?

• density = mass x density

• density = mass / volume

• density = mass + volume

• density = mass - volume

Calculate the density of the cube. Each side is 5 cm and its mass is 150 g.

Use the formula V = l x w x h

• 1.2 g/cm3

• 625 g/cm3

• 0.83 g/cm3

• 125 g/cm3

What units are used to measure density?

• g

• cm3

• g/cm3

• cm3/g

What units are used to measure volume?

• g

• cm3

• g/cm3

• mL
