Results and Discussion The purpose of the experiment was to identify an unknown liquid and an unknown solid by measuring their densities. Their densities were calculated by measuring the mass and volume of the substances. An electronic balance was used to measure mass and a graduated cylinder and 10 ml pipette were used to measure volume. The experiment was repeated three times. Table 1. Data for Unknown Solid #7 and Unknown Liquid for Group #5 Mass (g) Volume (ml) Density (g/ml)=M/V Solid Trial #1 7.620 g 2.0 ml 3.8 g/ml Solid Trial #2 7.621 g 1.9 ml 4.0 g/ml Solid Trial #3 7.622 g 2.0 ml 3.8 g/ml Liquid Trial #1 10.786 g 10.0 ml 1.08 g/ml Liquid Trial #2 10.401 g 10.0 ml 1.04 g/ml Liquid Trial #3 10.289 g 10.0 ml 1.03 g/ml Calculations Average The average density of the unknown solid was calculated as 3.9 g/ml. The average density of the unknown liquid was calculated as 1.05 g/ml. Standard Deviation
