Density Review

Using the picture, tell me which object is the least dense and why?

• The fish because he is in the middle

• The cork because it is floating at the top of the water

• The rock because it is at the bottom

• The cork and the rock because they have the same about of atoms.

Find the density of the cube. Hint- find the volume of the cube. The mass is given. Then plug both numbers into the formula: D= M / V

• 150 g/cm³

• 75 g/cm³

• 2 g/cm³

• 5 g/cm³

Find the volume of the cube. The mass of the cube is 240 g. What is its density?

• 60 g/cm³

• 3 g/cm³

• 240 g

• 4 g/cm³

What is the correct formula for solving density?

• D= M + V

• D= M x V

• D= M / V

• D= M - V

Calculate the density of the object below if it has a mass of 3g. (Hint: you need to find the volume.)

• 60 g/cm³

• 3 g/cm³

• 20 g/cm³

• 0.05 g/cm³

What is the density of the rock if the mass is 5g? (Hint: you will need to use the water displacement method to find the volume.)

• 0.2 g/mL

• 25 g/mL

• 75 g/mL

• 50 g/mL

What is the density of the steel rod if it has a mass of 40g? (Hint: use the water displacement method to find the steel rod's volume.)

• 10 g/mL

• 4 g/mL

• 40 g/mL

• 5 g/mL

Adding more of the same liquid to a container will change that liquids density

• True

• False

Which liquid has the greatest density?

• Corn oil

• Shampoo

• Antifreeze

• Maple syrup
