Density and Liquid Volume Review

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

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

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.

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.
