5 Density

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!
