What is Density?
Density is a measure of how much mass is packed into a given volume. It is commonly used to identify substances and determine whether objects will float or sink.
Density (D) = Mass (m) ÷ Volume (V)
Density units are typically g/cm³ or kg/m³.
Worked Example
A substance has a mass of 12 g and a volume of 3 cm³. What is the density?
D = 12 ÷ 3 = 4 g/cm³
The density is 4 g/cm³.
Practice Question
An object has a mass of 20 g and a volume of 5 cm³. What is the density?
