Suppose that you have a chunk of 10-pound aluminum and another chunk of a 50-pound aluminum. Which chunk has larger density

Density is a value for mass, such as kg, divided by a value for volume, such as m3. Density is a physical property of a substance that represents the mass of that substance per unit volume. It is a characteristic of a certain material. Since both are the same material, they would have the same density. Density is an intensive property which means its value does not depend on the mass of the material. Density is a ratio of two extensive properties (properties that depend on the amount of the material) which are mass and volume thus the result would be intensive properties.
