Approximating avogadro number lab Experimental guide and calculation review to approximate Avogadro's number. The experiment will test Avogadro’s number through two types of matter, small glass beads and an assigned fatty acid, and to use measurements of volume, mass, and To determine the approximate Avogadro’s number using glass beads and to approximate the size of an oleic acid molecule as well as the number of oleic acids in one mole of oleic acid, using several simple measurements. STOI 496/Approximating Avogadro’s Number Using Glass Beads and Monomolecular Film (f) Avogadro’s number (g) percent disagreement According to the standards of this experiment, (a) is the experimental result you calculated in Pre-Laboratory Assignment 3 Avogadro’s number is a number used to represent very large quantities, such as the number of atoms or molecules in a substance. To determine Avogadro’s Number, we will need to determine how many electrons have traveled from the cathode to the anode AND how many moles of electrons have traveled from the cathode to the anode. . Purpose/Objective: The purpose of this lab was to approximate Avogadro’s number by finding both the diameter of a glass bead and the diameter of a molecular film of stearic or lauric acid. e. The goal of this lab is to practice approximating Avogadro’s number, 6*10^ g/mol, which is used to express the number of molecules in a sample of macroscopic value. The goal is use the experiment as a tool to achieve Avogadro’s number in a physical manner. This can be used in various situations in the real environment as well, (i. Approximating Avogadro’s Number October 6, 2013 Section 103 Chemistry 1001 Wasantha Andrew Patek Purpose: The purpose of this lab is to measure objects that can be seen (glass beads), through macroscopic properties to find properties that cannot be seen (molecules) through microscopic properties. This lab is designed to use Hexane Stearic Acid to demonstrate the ability to calculate Avogadro’s number. how many molecules of acid you need to burn through an object). Approximating Avogadro’s Number October 6, 2013 Section 103 Chemistry 1001 Wasantha Andrew Patek Purpose: The purpose of this lab is to measure objects that can be seen (glass beads), through macroscopic properties to find properties that cannot be seen (molecules) through microscopic properties. You are to work in groups of four on both tasks. This exercise consists of two different strategies for experimentally determining Avogadro’s number. This experiment will be carried out in two parts. In this lab, you will use an interesting method using stearic acid to get a very rough idea of the value for Avogadro's number. This calculation will then be compared to a known value for percent error and accuracy. Gain an appreciation for the enormity of Avogadro’s number. Procedure: The Chemistry 1001 manual was followed for this lab on pages 33-41. Gain practice in deductive reasoning and problem solving. lbacv ldbye nsne oqaxl khnjeej fjcvakw poiqi jzj mjo fad
