Data were collected for trial 1 to determine the molar mass of a nonvolatile solid solute when dissolved in cyclohexane.

mass of cyclohexane 10.14g
mass of added solute .255g
kf value for cyclohexane 20.0
freezing point change δtf(°c) 3.04

what is;
mass of cyclohexane in solution (kg)
moles of solute, total (mol)
mass of solute in solution, total (g)
molar mass of solute (g/mol)

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.
