Purpose: To find the densities of an unknown solid and liquid in order to determine what they are.

Materials: Toluene(V) and Zinc(E)

Equipment: A stoppered flask, and an analytical balance

Safety: To begin the experiment, we wore our safety goggles.  We were careful with the chemicals as to not get it on our hands, or clothes.  When we were finished with our chemicals, we poured our “unknown liquid” into a container, specifically for that, located under the hood.  We put our metal in the designated place, rinsed our flasks and the stoppers, and left them to dry.

Procedure: In the 1st part of the experiment, we were trying to find the density of an unknown liquid.  To perform this experiment, we found the mass of the empty stoppered flask by weighing it on the analytical balance.  We then found the mass of the stoppered flask plus water.  By subtracting the mass of the empty stoppered flask from the mass of the stoppered flask filled with water, we found the mass of the water.  Next, we found the mass of the stoppered flask plus an “unknown liquid.” (V) By subtracting the mass of the empty stoppered flask from the ...
