Answer 2

Answer:

Mass is the amount of matter present in a substance. We can measure mass in grams or kilograms.

Everything which occupies space has a definite mass. Mass doesn't change in any condition either you live on earth or on mars your mass will remain constant.

Explanation:

Example:

Imagine a box of gold bars has a mass 50 kg on Earth. If the box is taken to the surface of the moon it won't change, it will remain same.

But if we are talking about the weight it changes because of gravity. On earth the force of gravity is equal to 9.8m/s2 and on moon it's some what less than the earth. So weight changes according to it's surrounding.
