Aflask with vinegar in it has a mass of 160 grams. a balloon with baking soda in it has a mass of 40 grams. the balloon is attached to the flask to seal the opening and the vinegar and baking soda mixes. the balloon inflates to a large volume. what will the total mass of the balloon and flask be after the balloon inflates? explain. a) less than 200 grams because the solid baking soda disappears. b) 200 grams, because all the atoms remain in the balloon or flask. c) more than 200 grams because the size of the balloon is so much larger. d) less than 200 grams because gases such as the one in the balloon are lighter than solids and liquids.

Following the Law of Conservation of Mass, you simply add the mass of both substances. Thus, 160 grams + 40 grams = 200 grams. So, even if initially, they are in liquid and solid form, they would still have the same mass even if they change phases, owing to that they are in a closed space.

 The total mass will be 200 grams. This experiment proves the Law of Conservation of Mass, meaning that the final mass it's not going to be forming more nor it's going to disappear. 
The total mass that we started (160+40) will be the same at the end of the reaction.
Since a gas is produced during the reaction it's better to use a ballon to collect this gas and that way preserving the mass.

It will still be 200 grams as all the atoms stay inside the balloon and flask
