Joseph EscotoCMWBMeasurement of DensityAbstract        This experiment was performed in order to determine the density of three different liquids labeled A,B, and C, a metal cylinder and a rubber stopper. The densities of the liquids were found using both a hydrometer and weight and volume measurements. For the solids we used the height and weight as well.        When using the hydrometer, the densities of the liquids were found to be .80 g/ml, 1.17 g/ml and 1.00 g/ml and when the weight and volume was used the densities were .78 g/ml, 1.14 g/ml and .88 g/ml. The metal cylinder had a density of 4.69/2.57 g/cc and the density of the stopper was 1.1 g/cc.        The identities of the liquid were water, ethanol and sodium chloride. The metal was aluminum.DefinitionsMass- The amount of matterVolume- Amount of space occupiedHydrometer- A floating device which sinks to different levels in order to determine densityDensity- The compactness of matter in a substance.
