Liquid Density Problem
Identify a liquid from its density.

You work for a company that has many different research groups, and your group has just developed a new food preservative which has been named "Compund A" Another group in your company has developed a new neurotoxin, which they have unfortunately also called "Compound A" An intern was reorganizing the chemical storage stockroom, and placed all the bottles labeled "Compound A" on the same shelf. You would like to begin testing the new food preservative, but don’t know which bottle contains the food preservative and which contains the neurotoxin. It would clearly not be a good idea to put neurotoxin into your food products. You have asked a theoretical chemist what to do, and he said that the preservative will have a higher density. Design an experiment to determine which bottle of "Compound A" contains the food preservative. (Note, the solution viewers and precise transfer mode have been disabled for this activity, you may find a volumetric flask useful in performing this experiment.)
