The amount of matter in a given space, or volume.

Explanation:
Density measures how much matter is packed into a given volume. It answers the idea of “how much stuff in a certain amount of space.” Mass is the total amount of matter, weight is the gravitational force on that matter, and volume is the amount of space the object takes up. Density links mass and volume with the formula density = mass ÷ volume, using units like g/cm^3 or kg/m^3. A larger mass in the same volume means higher density; a material with the same volume but less mass has lower density. So the phrase describing the amount of matter in a given space matches density.
