how much matter is in something?
mass
volume
density
weight

Explanation:

Mass is a measure of the amount of matter in an object. Volume is the amount of space an object occupies. Density is mass per unit volume ($\text{density}=\frac{\text{mass}}{\text{volume}}$). Weight is the force exerted on an object due to gravity ($F = mg$, where $F$ is weight, $m$ is mass, and $g$ is the acceleration due to gravity). The question asks about the amount of matter, which is mass.

Answer:

mass
