What is density?
Density is the mass per unit of volume of a substance.
Density measures the compactness in molecular arrangement in any substance which determines how heavy or light any substance is.
The density formula is
Examples of density include the following:
The density of water at
The density of iron at
The density of sodium metal at
In order to determine the density of a substance, you need to know its mass and its volume. Then divide its mass by its volume, remembering to divide the units as well.
Here is a video example of how to solve a density problem.
