In this experiment we will determine the density of a liquid and a solid by the procedure we have outlined. First we weigh an empty flask and its stopper. We then fill the flask completely with water, measuring
the mass of the filled stoppered flask. From the difference in these two masses we find the mass of water and
then, from the known density of water, we determine the volume of the flask. We empty and dry the flask, fill
it with an unknown liquid, and weigh again. From the mass of the liquid and the volume of the flask we find
the density of the liquid. To determine the density of an unknown solid metal, we add the metal to the dry
empty flask and weigh. This allows us to find the mass of the metal. We then fill the flask with water, leaving
the metal in the flask, and weigh again. The increase in mass is that of the added water; from that increase,
and the density of water, we calculate the volume of water we added. The volume of the metal must equal the
volume of the flask minus the volume of water. From the mass and volume of the metal we calculate its density. The calculations involved are outlined in detail in the Advance Study Assignment.
