Directions: Read each question carefully and write your answer on the line. Use the diagram to help you.

Example

An object has a mass of 72 g and a volume of 8 cm³. What is its density?

Answer: 9 g/cm³

RememberDensity

mDVdensity = mass ÷ volumemass = density × volumevolume = mass ÷ densityWater is 1 g/cm³: denser things sink.
  1. 1

    An object has a density of 0.9 g/cm³. Will it sink or float in water (1 g/cm³)?

    ?object: 0.9 g/cm³water: 1 g/cm³
  2. 2

    A material has a density of 7.9 g/cm³. What is the mass of 24 cm³ of it?

    D = 7.9 g/cm³V = 24 cm³m = ?
  3. 3

    An object has a density of 0.5 g/cm³. Will it sink or float in water (1 g/cm³)?

    ?object: 0.5 g/cm³water: 1 g/cm³
  4. 4

    A material has a density of 2.7 g/cm³. What is the mass of 26 cm³ of it?

    D = 2.7 g/cm³V = 26 cm³m = ?
  5. 5

    An object has a mass of 25 g and a volume of 10 cm³. What is its density?

    m = 25 gV = 10 cm³D = ?
  6. 6

    A material has a density of 11.3 g/cm³. What is the mass of 32 cm³ of it?

    D = 11.3 g/cm³V = 32 cm³m = ?
  7. 7

    An object has a mass of 4.8 g and a density of 0.8 g/cm³. What is its volume?

    m = 4.8 gD = 0.8 g/cm³V = ?

    A material has a density of 1.5 g/cm³. What is the mass of 32 cm³ of it?

    D = 1.5 g/cm³V = 32 cm³m = ?
  11. 11

    An object has a mass of 3.6 g and a volume of 4 cm³. What is its density?

    m = 3.6 gV = 4 cm³D = ?
