A chemist walks into a lab and finds a strange rectangular prism with the dimensions of .02 m, 50 cm, and 25 mm. He knows the density of gold is 19.3/ml, the density of silver is 10.49 g/ml and the density of Platinum is 21.45 g/ml. If the rectangular prism weighs 4.83 kg, what is the block made of ?

Ais the correct answer

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.
