Student: Keila Dukuze Date: Feb/10/2013 Lab# 3 Section: 110 Pre-Lab Report Determining the Density of Various Liquids and Solids The purpose of this experiment is to determine the weight (density) of certain liquids and solids in chemistry. These liquids include; Water‚ Hexane‚ Carbon Tetrachloride‚ and solids include; Copper‚ Zinc‚ Lead and‚ Aluminum. It’s important to know the weight of these products so you can properly conduct experiments and make clear observations. Different

Abstract Molar volume is the volume that one mole of gas occupies when temperature and pressure are kept constant. The molar volume of a gas can be determined through evaluating how much gas is given off when the number of moles of the substance is known. To find the volume of gas that will be used to calculate the molar volume‚ the process of water displacement can be used. Reference Citation Cesa‚ J. (2002).

Introduction Molar volume is the name given to the volume that one mole of any gas occupies at standard temperature and pressure. In chemistry‚ many of the materials worked with are gases. It is often easier to measure the volume of a sample of gas‚ rather than determine its mass. The main purpose of this lab is to determine the molar volume of hydrogen gas experimentally in order to compare it to the theoretical molar volume of ideal gases. In this experiment‚ a known mass of magnesium is reacted

Lab One: Laboratory Techniques and Measurements Abstract The Lab One was done on Laboratory Techniques and Measurements. The first experiment with my Lab partner; we got opportunity to experiment how to conduct measurements in length by using metric conversion. We started in cm units and changed into mm by x10‚ and moving decimal point x1 to right. To find in meter we moved from cm to meter two decimal points to the left or double check our self divided by 100 and all records in data

Lab 1- Measurements of a Table ABSTRACT: The purpose of this experiment was to determine the value of the acceleration of a free falling object and to describe the range of experimental values. Within the experiment the items used to help provide the conclusion that 2/3 or our values fell within the 9.62m/s^2- 9.78m/s^2 range was a Vernier data-collection interface‚ Logger Pro Application and the apparatus Photogate. The results found within the 30 trial periods were all precise

MEASUREMENT OF PHYSICAL PROPERTIES: DENSITY Introduction According to the definition Density is the physical property that allows us to compare the mass of substances for a specific volume. In this Lab activity that took place in Deree College‚ Agia Paraskevi Campus we deal with the density of solids and density of liquids. The main purpose of this experiment is to understand what in reality density means‚ how we can measure it‚ how useful it is‚ what is the difference between density of solids

Then‚ we used the
Premium Mass Measurement Uncertainty
In this lab‚ there was a comparison between accuracy and precision of densities measured by volume. Mass measurements are often used units in the metric system. Volume can be examined a borrowed unit. The volume measurements were made in mL. Every measurement had a level of hesitancy affiliated with it. The experiment could feel uncertain from the object used for measurement and from the accuracy of the person doing the measuring of the volume. Because of this uncertainty‚ the experiment must be

Kevina Smith Lab 1: Microscopy and the Metric System Part A: Microscopy Purpose The purpose of this experiment was to learn how to use a microscope correctly and perform wet mount slides accurately‚ thus becoming more familiar with the microscope. Hypothesis It would be hard to use the microscope without any kind of previous training and the parts of the microscope and their functions must be learned in order to use it properly.
