The mass of a sand tiger shark is about 9.1 • 10^1 kg. The mass of a whale shark is about 20.6 metric tons. How
many sand tiger sharks would it take to equal the mass
of a whale shark? (1 metric ton = 1,000kg)

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant. 

So3 that’s what i think
