CHEM HELP??? 3.10-g mixture of lead nitrate and potassium nitrate are mixed with an excess solution of sodium chloride. There is a precipitate with a mass of 1.10 grams. Calculate the mass percent of the lead nitrate in the solution (remember the amount the lead nitrate solution is given in mass not in L). Show factor label for stoichiometry. First write the net ionic equation.

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. 

What are the statements?

The answer is false because: gravitational force is independent of medium and depends only on the masses of the two objects and the distance between them
