A flask 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.

 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.
