I. Results and Discussion In order to determine the densities of an unknown liquid and an unknown solid the equation D = m/v was used. Mass was determined through the use of an electronic balance, and volume was determined through measuring 10mL of the unknown liquid in a pipette accurate to 10±0.04 mL, and volume of the unknown sold was determined through displacement in a graduated cylinder accurate to ±0.3 Three experimental trials were performed. The data and calculated results were tabulated (Tables 1 and 2). Table 1: Unknown Liquid 5 Trial Mass (g) Volume (mL) Density (g/mL) 1 10.801 10.02 1.078 2 10.824 10.05 1.077 3 10.805 10.01 1.079 Table 2: Unknown Solid 4 Trial Mass (g) Vol initial (mL) Vol with solid (mL) Vol of solid (mL) Density (g/mL) 1 10.042 10.61 14.35 3.74 2.69 2 10.042 9.70 13.32 3.62 2.77 3 10.042 10.46 13.96 3.50 2.87 Density was calculated using the equation mentioned above, D=m/v.
