Question

What quantity measures the amount of matter in an object

Answer 1

Mass

Step-by-step explanation:

Mass is a measure of the amount of matter that an object contains. The mass of an object is made in comparison to the standard mass of 1 kilogram.

Answer 2

Mass is a measure of the amount of matter in an object, so the mass of an object is constant. Weight is a measure of the force of attraction of the earth acting on an object. The weight of an object is not constant. Mass is a more fundamental quantity than weight.
