Unformatted text preview: 2-1-06Chem 1M Section 01HExperiment #2Using Various Forms of Volume Measurement to Determine the Density of MetalCylindersAbstract:In this experiment, the density of four different metal cylinders, aluminum, brass, hollow aluminum, and mixed brass and aluminum were determined using three different methods of measurement which were geometry, water displacement, and pycnometry. All three methods were used to determine the density of the pure brass and aluminum cylinders, while for the hollow and mixed cylinders only pycnometry was used since this is the most accurate form of measuring density. The density of brass was found to be about 8.4 g/mL, while aluminum was about 2.7 g/mL. This is within range of the actual densities of brass and aluminum, which are 2.7 g/mL and .53 g/mL respectively. The void volume of the hollow aluminum cylinder was determined to be .01 mL. The percentage of each metal in the mixed cylinder was 7% aluminum, and 93% brass, which is logical since the mass of the cylinder was closer to the weight of brass than aluminum.is logical since the mass of the cylinder was closer to the weight of brass than aluminum....
