Answer 1

The correct definition of mass is "the amount of matter in an object." Mass is a measure of the quantity of matter, and it is often confused with weight, which is the force that gravity exerts on that mass. The other options pertain to concepts of gravity and volume but do not define mass itself. Therefore, the best answer is:

**The amount of matter in an object.**
