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

Density Lab Partners: Betty Alcaraz Date: 9/10/13 Teacher: Wright Class: 7th period Introduction/Purpose: To determine the densities of unknown substances. Pre-Lab: 1. Which is heavier‚ a pound of feathers or a pound of lead? a. A pound of lead. 2. What is the density of a mineral if 427 g of the mineral occupy a volume of 35.0cm3? b. 12.2g/cm3 3. The water level in a graduated cylinder stands at 20.0 mL before and at 26.2 mL after a 16.74 g metal sample

Practical Report Experiment 1 Abstract In this experiment we found that you can calculate the density of elements with close presotion with crude experiments Introduction The aim of this experiment was to see how close you could measure the density of atoms with crude experiments. The second part of the experiment dealt with Solubility of large ions and their Hydration enthalpy. Hydration enthalpy is the enthalpy change when 1 mole of an ionic substance dissolves in a solution to give a solution

Density: Using Experimental Techniques to Solve an Inquiry based problem ABSTRACT The topic of this experiment is Density. The objective is to find two ways in which the density of a given object can be determined‚ and to find out which of the two ways is more accurate and hence better to use in such a case. The two methods used in this experiment are finding the dimensions of the object and water displacement. These are two ways of finding the volume of an object‚ and they were chosen since

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

Period 7 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

Experiment 1: Density | Purpose: To determine the density of the following liquids and solids. Data/Observation: Part A Sample | Distilled Water (g) | Methanol (g) | Glycerol (g) | Mass of empty cylinder | 41.1 g | 40.4 g | 41.1 g | Mass of cylinder + liquid | 51.2 g | 48.2 g | 53.8 g | Mass of liquid | 10.1 g | 7.8 g | 12.7 g | Calculations: Density of liquid = Mass/Volume = g/mL Distilled Water = 10.1g/10mL = 1.01 g/mL Methanol = 7.8g/10mL = 0.793 g/mL Glycerol = 12.7g/10mL
