Chemistry Density

The mass of a mystery liquid is 30g and its volume is 5mL. Calculate its density.

• 6 g/mL

• 150 g/mL

• 25 g/mL

• 35 g/mL

What two things must you know about a substance to calculate its density?

• mass and volume

• mass and weight

• volume and weight

• mass and gravity

Will an object that has a density of 3.4 g/cm3 float or sink in water? The density of water is 1.0 g/mL.

• sink

• float

• neither

Which one of the following statements is correct?

• Object A is more dense than Liquid 1.

• Object B is more dense than Liquid 2.

• Object C is more dense than Liquid 2.

• Object C is less dense than Object B.

Starting from the bottom, label the most to least dense.

Aiden and Noah are comparing two objects. "The balls have the same ​ (a)   , but the foam ball has more ​ (b)   .

So, the ​ (c)   has more density.

• mass

• volume

• marble

• foam ball

Answer explanation

Aiden and Noah state that the balls have the same mass but the foam ball has more volume. Since density is mass divided by volume, the marble must have more density than the foam ball.

The balls have the same ​ (a)   , but the foam ball has more ​ (b)   .

So, the ​ (c)   has more density.

• mass

• volume

• marble

• foam ball

Look at the picture and match the following:

• A

• Density

  .97g/ml

• C

• Density

  0.72 g/ml

• B

• Density 1.15g/ml

If you were told that Liquid 2 (the middle layer) was water, what would that tell you about the densities of Object B, Liquid 1 and Object A?

• The density of densities of Object B, Liquid 1 and Object A are more than 1.0 g/mL.

• You cannot predict density using the information given.

• The density of densities of Object B, Liquid 1 and Object A are less than 1.0 g/mL.
