Problems. to receive full credit, you must show all your work (gas law constamt r-00821 atm/mol k or 62.4 l torr/mol k) 1. (10 points) a sample of nitrogen gas occupies a volume of 8 50 l. at 0.980 atm. what volume does the gas occupy if the pressure is increased to 1.30 atm? 2. (10 points) a helium sample at 25 c has a volume of 1.82 l. if the pressure and amount of helium remain unchanged what will the volume of the gas be at 50°c? (10 points) a 0.85 mol of a gas has a volume of 758 torr and a volume of 21.0l. what will the volume be if the amount is increased to 1.00 mol and the pressure remains 3. unchanged?

Variables,control,conclusion and finally scientific theory

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.
