Final answer:
The property that describes the amount of matter in an object is mass.
Step-by-step explanation:
The property that describes the amount of matter in an object in a given volume is mass.
Mass is a measure of the amount of matter in an object and it can be measured using a balance scale. For example, a 1 kg block of iron has more matter than a 500 g block of wood.
Volume, area, and density are related properties, but they do not directly describe the amount of matter in an object.
