Which statement describes mass?

Explanation:
Mass is the amount of matter in an object—the amount of stuff it contains. It’s the quantity that determines inertia, or how resistant the object is to changes in motion, and it stays the same no matter where the object is (Earth, Moon, or space). The standard unit is the kilogram. This differs from weight, which is the gravitational force acting on mass and changes with gravity. Volume describes how much space an object occupies, and the state of matter refers to whether something is solid, liquid, or gas. So mass is best described as the measure of the amount of matter an object has.
