Learning Objectives

  • In this skill we will learn the relationship between density (D), mass (m), and volume (V).
  • Mass is "how much stuff" is inside an object, and is usually measured in g.
  • Volume is "how much space" an object takes up, and is usually measured in cm³.
  • Density is "how tightly packed" the stuff inside an object is, and is usually measured in g/cm³.

Equations

  • Density: D = m / V

Tips

  • Be sure to look at the units carefully - they are really helpful!For example, if you see a quantity is measured in g/cm³, it must be density!
