Question

paul and karen were studying physical and chemical properties of matter. they determined that the mass of a sample was 50 grams. which sentence best states how mass describes matter?
o the mass of a substance is a way to measure the amount of matter it contains.
o mass is a way to measure the force of gravity on a substance.
o the mass of a substance may change, based on its location.
o mass is a chemical property of a substance.

Explanation:

Mass is a fundamental property in physics. It is defined as the amount of matter in an object. Chemical properties involve reactions and changes at the molecular level, which mass is not. Weight (related to gravity) can change with location, but mass remains constant. So, mass is about the quantity of matter.

Answer:

The mass of a substance is a way to measure the amount of matter it contains.
