Performed: July 10‚ 2013 Group No.: 4 Date Submitted: July 17‚ 2013 Experiment #1: Measurements INTRODUCTION Density is a physical property of matter‚ as each element and compound has a unique density associated with it. The unit of Density is g/cm3 or g/mL. It is used to measure thr relative “heaviness” of objects with a constant volume. As defined‚ the formula for Density is Mass over Volume (ρ=m/v) and it can be rearranged to get the Volume (v=m/ρ) or Mass (m=ρv) of a certain substance

CH.15 Review Questions Growing Tensions Between North and South 1. How did the North and the South differ in the 1840s? In the 1840s‚ the North and the South differed because the North had slaves and the South didn’t. 2. How did Southerners react to the Wilmot Proviso? The way the Southerners reacted to the Wilmot Proviso was that they were mad because the government was taking what Southerners thought was their property. 3. What was Stephen A. Douglas’s role in passing the

9/17/13 The Density of Metals Lab BACKROUND: Density is a constant relationship between the mass and volume of a specific type of matter. Measurements of both mass and volume can be obtained for a metal sample. The relationship can be shown graphically by plotting the volume of a sample on the horizontal x-axis and the mass of the sample along the vertical y-axis. Plotting the values for several samples‚ a linear relationship can be seen for a density (slope=density). PURPOSE: During this lab‚ you will

Discussion and Conclusion In this lab‚ a submarine Adventure: Density Saves The Day‚; I had made many of the calculation for the best result of the lab. My calculations section contains: the volume of the unknown metals‚ where I figure out the volume of each metal so that I will be able to determine its density in order to find its identity; the density of unknown metals‚ where I figure out the density of each metal so that I will be able to determine its identity; percent error between known

Hamza Aziz General Chemistry I Lab 09/12/2007 Lab 7 Density of Sprite and Diet Sprite Abstract: The density of regular Sprite was found to be 1.037 +/- g/mL. compared to Diet Sprite which was 0.9965 +/- g/mL. Among the three volumetric glassware Pipette was most precise (ó=0.0016 g/mL). Burette was the second best (ó=0.0023 g/mL) and graduated cylinder was the least precise (ó= 0.007 g/mL). Density was found to be intensive property. The slope of the graph of mass against volume was 1.05

Lab #2 Determination of Density Britney Williams Chemistry 121 Dr. Yu 1/29/13 Purpose: To determine the densities of aluminum and zinc cylinders Density is the relationship between the mass of an object and its volume. Sometimes density can be easy to sense. If two objects have exactly the same shape and size‚ the denser one may feel heavier. If their densities are close together‚ it can be hard to tell the difference. It gets really tough if you are dealing with materials that have very different

Nutrition Density Essay After having calculated the nutrient density of seven food groups in a spreadsheet‚ the food group that came to have the highest Nutrient Density was the vegetable group obtaining an average of 7.76712 Nutrient Density. The food group that came to have the lowest Nutrient Density was the “junk food” group‚ having an average of 0.24845 Nutrient Density. One of the factors that contribute to foods having a high or low Nutrient Density is the amount of calories. I noticed that
