Consider the following scenario: At the end of lab, a student chooses to mix the following solutions together as general chemical waste.

25.0 mL of 0.200 M HA (strong acid)
200.0 mL of 0.100 M HX (strong acid)
500.0 mL of 0.0100 M D(OH)2 (strong base)
200.0 mL of 0.100 M MOH (strong base)
What can you say about the resulting solution? You may wish to include commentary on whether the solution is net acidic, basic, or neutral. You may wish to talk about remaining/resulting concentrations. A full credit answer will provide solid, specific details to support the commentary.

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.
