Unformatted text preview: Experiment 1: Density of a Liquid and a Solid General Chemistry I and II Lab Manual Dakota State University Page 49 of 232 Return the liquid to the first beaker, and dry the second beaker. Using a clean and dry graduated cylinder, measure out 20.0 ml of the unknown liquid and put it into the second beaker. Again, get the mass of the second beaker with the liquid in it. Once again, return the unknown liquid to the original beaker. Measure out 20. ml of the unknown liquid using an Erlenmeyer flask. Determine the mass of the beaker with the liquid in it. Dispose of the unknown liquid as instructed. Part II: Density of an Unknown Solid From time to time, a chemist has to be clever enough to find an indirect method to measure some quantity. For example, how would one go about measuring the volume of an unusually shaped solid. Archimedes faced this problem when be had to determine the density of a crown for the king in order to determine whether or not the blacksmith stole some of gold and...
