A student mixes 120 grams of vinegar and 15 grams of baking soda in an open beaker (total starting mass = 135 grams). Rapid bubbling occurs. After fizzing stops, the mass of the contents in the open beaker is measured at 131 grams. Why did the measured mass decrease by 4 grams?

4 grams of mass were destroyed during the chemical reaction. 4 grams of carbon dioxide gas escaped into the surrounding air. Baking soda loses all of its mass when dissolved. Vinegar turned into light energy and vanished.

Correct Answer:

4 grams of carbon dioxide gas escaped into the surrounding air.
