Density is a property due to the nature of a particular material. The density of a particular material is not dependent on the amount of the material examined. Therefore, density is a characteristic property. It is a ratio of the mass of an object to its volume. The mathematical equation is
Density is a property that must be computed from measurements. In the lab, the mass is usually measured by weighing the material on a balance. For a liquid, the volume is usually measured using a measuring device called the graduated cylinder. Typical units of density measurements are:
