Which term refers to the amount of matter in an object?

• A. Weight
• B. Volume
• C. Mass
• D. Density

Answer: (C)

Mass is the amount of matter in an object. This makes mass an intrinsic quantity that doesn’t change with location or gravity, so it stays the same whether you’re on Earth or the Moon. It’s measured with a balance and expressed in units like grams or kilograms. Weight, by contrast, is the force of gravity acting on that mass and can vary with gravity. Volume is the amount of space the object occupies, and density is how much mass is packed into that volume (mass per unit volume). Since the question focuses on the amount of matter, the term that fits best is mass.
