How is Lab Glassware Used? Zhengqian Li Lab TA: Jinwei CHM 113 W 8:30am Introduction
The goal of this lab was to use different glassware to accurately measure multiple volumes of water, and to then use the collected data to calculate the density and percent variation in density. We hoped this would accomplish the task of showing us the different attributes of the glassware and the varying accuracy levels they all possess. During the lab we used three different types of glassware. We used a 50ML beaker, a burette and a 10ML graduated cylinder. Using this equipment, we measured three different volumes of water for each experiment in order to record accurate data. In theory, as we use glassware with more accurate measurements of volume, we get a more accurate density calculation. The equations we used for this experiment are as follows: Density = Mass / Volume [(Theoretical Density - Experimental Density) / Theoretical Density] * 100 = Percent Error Procedure
