The volume of an irregular solid can be found from its displacement in a known volume of water. Find the volume of an irregular solid if 10.00 mL water in a 25-mL graduated cylinder rises to 17.3 mL when the solid sinks to the bottom of the cylinder and all air bubbles rise to the surface. (Remember to put a space between your numerical value and the unit.)

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.
