Unlike weight, which is the force of gravity acting on an object and changes depending on the gravitational field, mass remains constant everywhere in the universe. Since the mass of the body is 100 kg on Earth, it will remain 100 kg on the Moon, regardless of the change in acceleration due to gravity.
