Some tomato ketchup accidentally got onto a piece of white fabric. Your mother suggested that lemon juice, baking soda, or vinegar would be good for removing the tomato stain. Plan and design an experiment that can be used to investigate which of the three substances is most effective in removing the tomato stain. 1. Write a hypothesis for your investigation
2. Identify the dependent, independent, and controlled variables.
3. Outline a proposed method for the experiment you would conduct.
4. What data would be collected? Suggest a suitable way(s) for recording your data.
5. Identify ONE (1) possible source of error and ONE (1) precaution.

Please if you see this help me answer these questions.

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.
