Energy density

Objective: Determine the density of a metal sample by using the density formula, Density(D)= mass(m)/ Volume(V), and the water displacement method. Determine the precent error of calculated density. Procedure: Part 1: First, all materials was gathered: metal sample (aluminum), empty jar, electronic scale with 0.01 accuracy, calculator, thermometer, paper towels and lab worksheet. A sink was also needed for tap water. The mass of the empty jar was weighted and recorded in the lab worksheet. The

Density and SG by Hydrometer Method Objective The purpose of this practical is to determine the specific gravity and density of samples of methylated spirit of different concentrations, using a hydrometer. Introduction Theory Specific gravity (SG) is defined as the ratio between the density of a liquid to the density of water at a temperature of 4oC and pressure of 1 atm. It is of great importance when quoting the specific gravity of a substance to refer to the temperature and pressure at which

The density of water is its mass divided by its volume. In this case, the mass of water was determined by subtracting the final mass of the glassware with water by the initial mass of the glassware without water. The volume was determined by observing closely which line (marked on the sides of each glassware) the water reached and reporting the most precise measurement. Based on the class data, the average densities of water and its standard deviations were: 50-mL beaker – avg: 0.90 g/mL, stand dev:

mass, length, and temperature of a wide variety of items. To learn how to calculate density and concentration of dilutions. Procedure: I used a ruler, thermometer, and scale to take measurements. I used a graduated cylinder, short step pipet, scale, and ruler to determine volume and density. I used a volumetric flask, graduated pipet, pipet bulb, scale, and glass beaker to determine concentrations and densities of various dilutions. Data Tables: |Data Table 1: Length

During this lab I will learn how to measure length, temperatures, volume, density, and mass using laboratory equipment. I will be using laboratory equipment to prepare dilutions and calculate them while using an algebraic formula. 3. Procedure: In order to perform this lab I needed the following materials: a metric ruler

Objective: The objective of this lab was to calculate the densities of various objects using different techniques. Procedure: <ol> <li value="1"> The mass of the 100-ml. Graduated cylinder was measured without water or rubber stopper. <li value="2"> The mass of the 100-ml. Graduated cylinder was measured without water but with the rubber stopper. <li value="3"> The mass of the metal cylinder was measured. <li value="4"> The 100-ml. Graduated cylinder, with rubber stopper was filled

of the water by seeing how much the water rises but it did not rise from 10 ml mark because no object or weight was in the water. The density of the water is mass divided by volume. Our volume was 1 ml and our, mass was 9.8g, and after dividing those two numbers we got a density of .98g/ml. But the density of pure water is 1.0, and the density we got for the density of tap water which is not pure water, is supposed to weigh more than the pure water. In Lab 2 part 3 the wt of the 10 ml of salt water

Density is the measurement of an object that has a relative mass and is divided by a specific volume. Mass is the amount of matter an object possesses. Volume is the amount of space of an object occupies (solid, liquid or gas.) In chemistry the term density can be described as a physical and intensive property of matter. The term intensive property means, it is independent on the size and amount of a substance. Many chemist compare different types of densities of elements and substance with water

much solute is in a solution. In order to find the concentrations, both substances needed to be weighed and measured and finally have their data plugged into the appropriate formulas for molarity (mol solute/L solution) and density (m/v). To find the relationship between the density and concentration, a calibration curve was used. A calibration curve is a graph with a best fit line, revealing the connection between the two factors. Therefore,
