What is the term for the amount of matter in an object?

The correct answer is mass, which refers to the amount of matter present in an object. Mass is a scalar quantity and is typically measured in kilograms or grams. It is an intrinsic property of matter, meaning it does not change regardless of an object’s location or the gravitational field acting upon it.

Volume, on the other hand, refers to the amount of space an object occupies, typically measured in cubic centimeters or liters. Weight is the force exerted by gravity on an object and can vary depending on the gravitational pull encountered. Density is defined as mass per unit volume and is a measure that relates how much mass is contained in a given volume of a substance but is not a direct measure of how much matter is present as mass is. Thus, mass is the most precise term for describing the quantity of matter in an object.
