Which quantity describes how tightly packed matter is inside an object?

Answer 1

The quantity that describes how tightly packed matter is inside an object is called density. Density is defined as the mass of an object divided by its volume and is typically expressed in units such as grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³). A higher density indicates that the matter is more tightly packed, while a lower density indicates that the matter is more spread out.
