09-20-06 CHM 102 Lab Report Experiment 1: Measuring the Density of Pepsi INTRODUCTION: In this experiment, I will be finding the densities of both Pepsi and Diet  Pepsi. In order to do this, I will have to find the mass and volume of a certain  amount   of   the   liquid.   Using   four   different   pieces   of   lab   equipment,   I   will  determine the mass and volume of the liquid, using a different item each time.  Although the volume will be the same with each item, the precision and accuracy  will differ somewhat.  Water and sugar are the main ingredients of Pepsi, the carbonated drink  that most people recognize. Therefore, the density of Pepsi is mostly due to its  sugar content. Diet Pepsi, however, contains an ingredient called Aspartame. This  is   a   low-calorie,   artificial   sweetening   agent   that   when   added   to   Diet   Pepsi,  provides a higher level of sweetness per gram than sugar. Even though Diet Pepsi  has a very small amount of aspartame added to it, it still has the same sweetness  level as regular Pepsi. EXPERIMENTAL PROCEDURE: The four pieces of equipment that I will be using in this experiment will be  a beaker, a graduated cylinder, a buret and a pipette. To find out the mass of the  liquid, using a balance, I will record the weight of the item being used first. After  that, I will pour a certain amount of the liquid into the item and record the weight.  Now that I have recorded both weights, I can find the mass of the liquid by  subtracting the weight of the item from the weight of the item and the liquid  together.   I   do   this   certain   procedure   again   with   each   individual   piece   of  equipment.
