Understand the difference between intensive and extensive properties: Intensive properties do not depend on the amount of substance, while extensive properties do depend on the amount.
Recall that density is defined as mass divided by volume, \(\rho = \frac{m}{V}\).
Since both mass and volume are extensive properties, but their ratio (density) remains constant regardless of the sample size, density does not change when the amount of substance changes.
Recognize that because density does not depend on the quantity of material, it is classified as an intensive property.
Note that density is also a physical property because it can be measured without changing the chemical identity of the substance.
