Roshni Sheth CH 116-M3 Partners: Kaity Brown, Chris Suda September 2, 2009 Density and Graphing Lab Report 1. Description of Procedure Used In this lab experiment, each lab partner uses three different types of glassware (a 250 mL beaker, a 10 mL graduated cylinder, and a graduated pipet) to determine the density of water by taking its volume and mass. The first step of the experiment is to use a balance to take the mass of another beaker that is used as a container and record it. The second step is to fill the 250 mL beaker with water and record its volume as the initial volume. Afterwards, the students pour a random amount of water from the 250 mL beaker into the container. The students determine the new volume of water in the beaker and record it as final volume. The students find the volume delivered by subtracting the final volume from the initial volume. Then, the students mass the container with water using a balance, record it as the final mass, and subtract the initial mass of the container to find the mass of the water alone to record it as the displaced mass. This process is done a total of 3 times by each lab partner. Next, the students move on to the 10 mL graduated cylinder
