Density and Treatment of Data Dang Quang Nguyen Chemistry 1A Spring 2020 September 21, 2020 Objective/Purpose In this laboratory, we perform three experiments. First, we will determine the density of a solid. Second, we will calibrate the volume of o pipette. Finally, we use the calibrated pipette to determine the density of an unknows liquid. Theoretical This section includes background information necessary to complete the lab. Include all mathematical formulas, as well as all chemical reactions occurring in the experiment. There is no need to explain the Chemical equations or the Mathematical Equations. Example:
Data Table 1: Determination of the Density of a metal Trial 1 Trial 2 Trial 3 Mass of solid (g) 17.5211 17.5211 17.5211 Volume of water and solid (mL) 54.9 55.2 56.0 Volume of Water (mL) 49.8 49.2 49.9 Volume of Solid (mL) 5.1 6.0 6.1 Density of Solid (g/mL) 3.4 3.0 2.9 Table 2: Calibration of Pipette Trial 1 Trial 2 Trial 3 Mass of flask + H 2 O (g) 59.394 69.120 78.893 Mass of flask (g) 49.593 59.394 69.120 Mass of H 2 O (g) 9.801 9.726 9.773 Temperature of water ( o C) 23.8 23.8 23.8
