In Trial 1 80 63 17 In Trial 1 mass of metal cylinder is 17. The mass of the metal cylinder can be determined subtracting the mass of the empty stoppered flask from the mass of the stoppered flask with the metal cylinder. In Trial 1 48 58 In Trial 1 density of liquid B is In Trial 2 48 58 In Trial 2 density of liquid B is To calculate the density of the unknown metal cylinder, first we must determine the mass and volume of the metal cylinder. With a known mass and volume of liquid B the density of liquid B is calculated using the following formula Density Mass Volume. In Trial 2 63 48 In Trial 2 mass of liquid B is 48. In Trial 1 63 48 In Trial 1 mass of liquid B is 48. Mass of the stoppered flask filled with liquid B minus mass of the empty stoppered flask equals mass of liquid B. In Trial 1 58 58 In Trial 1 volume of pycnometer is 58 In Trial 2 58 58 In Trial 2 volume of pycnometer is 58 Having determined the volume of the pycnometer, in order to determine the density of unknown liquid B it is necessary to determine mass of liquid B. Having determined the density and the mass of the water, the volume of the water in the pycnometer was calculated using the following formula Volume Mass Density. The temperature of the water during each trial was used to the density of the water on the internet. In Trial 2 mass of water in pycnometer is 58. In Trial 1 122 63 58 In Trial 1 mass of water in pycnometer is 58. In each trial, mass of the stoppered flask filled with water minus mass of the empty stoppered flask equals mass of the water. CALCULATIONS: To determine the volume of the pycnometer used throughout Experiment 1 the mass of the water used to fill the flask had to be determined. DATA: The data collected and calculated that was used to determine the volume of the pycnometer used throughout the experiment is represented in Table 1: Table 1 Mass of empty stoppered flask Mass of stoppered flask and water Mass of water (calculated) Temperature of water Density of Trial 1 63 122 58 0 Trial 2 63 122 58 0 of water based on temperature, retrieved from ymouth The data collected and calculated that was used to determine the density of unknown liquid is represented in Table 2: Table 2 Mass of stoppered flask and liquid B Mass of liquid (calculated) Volume of liquid B (from Table1 calculation) Trial 1 48 58 Trial 2 48 58 The data collected and calculated that was used to determine the density of unknown metal cylinder is represented in Table 3: Table 3 Mass of stoppered flask and metal Mass of stoppered flask, metal, and water Mass of metal (calculated) Mass of water (calculated) Volume of water (calculated) Volume of metal (calculated) Trial 1 80 133 17 52 52 6 Trial 2 80 133 17 52 52 6 For original sheets of data collected see attached pages. EXPERIMENTAL PROCEDURE: See attached pages. design, Experiment 1 provides the data necessary to calculate the density of the unknown liquid and solid. After obtaining the mass and volume of the unknown sample we can calculate the density of that unknown liquid or solid. The mass of the unknown samples are accurately obtained weighing and using the measuring difference method. Given the specific density of water at various temperatures and solving the density formula for volume we can accurately determine the volume of our container. At any specified temperature and pressure the density of a sample is constant. The density of a subject is expressed as a ratio of the mass to volume in the following formula: Density Mass Volume. DISCUSSION: Density is a standard physical property of a liquid or solid. Preview text Experiment 1 Lab Report Determining the Densities of Liquids and Solids OBJECTIVE: The objective of Experiment 1 was to find the density of an unknown liquid and an unknown solid.
