Example

An object has a mass of 30 g and a volume of 15 cm³. What is its density?

Answer: 2 g/cm³

RememberDensity

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

    An object has a mass of 300.2 g and a density of 7.9 g/cm³. What is its volume?

    m = 300.2 gD = 7.9 g/cm³V = ?
  2. 2

    A material has a density of 7.9 g/cm³. What is the mass of 38 cm³ of it?

    D = 7.9 g/cm³V = 38 cm³m = ?
  3. 3

    An object has a mass of 173.8 g and a volume of 22 cm³. What is its density?

    m = 173.8 gV = 22 cm³D = ?
  4. 4

    A material has a density of 2.7 g/cm³. What is the mass of 8 cm³ of it?

    D = 2.7 g/cm³V = 8 cm³m = ?

    An object has a density of 3 g/cm³. Will it sink or float in water (1 g/cm³)?

    ?object: 3 g/cm³water: 1 g/cm³
  8. 8

    An object has a density of 2.5 g/cm³. Will it sink or float in water (1 g/cm³)?

    ?object: 2.5 g/cm³water: 1 g/cm³
  9. 9

    A material has a density of 4 g/cm³. What is the mass of 12 cm³ of it?

    D = 4 g/cm³V = 12 cm³m = ?
  10. 10

    A material has a density of 0.9 g/cm³. What is the mass of 10 cm³ of it?

    D = 0.9 g/cm³V = 10 cm³m = ?
  11. 11

    An object has a density of 0.8 g/cm³. Will it sink or float in water (1 g/cm³)?

    ?object: 0.8 g/cm³water: 1 g/cm³
  12. 12

    A material has a density of 11.3 g/cm³. What is the mass of 38 cm³ of it?

    D = 11.3 g/cm³V = 38 cm³m = ?
