The Density of an Egg Tony Biallas and Mitchell Gohan LB171L Sec.8 Sept. 8 th 2010 Megan Courtley and Kelly Witt Dr.Maxine Davis Procedure The goal of the lab was to find the most accurate density of an egg using three of the five different measurement instruments. The lab began with forming a table to record the mass, density and volume of an egg using the different instruments. In order to find the density of the egg, a 50mL beaker was filled with water and the egg was placed inside. Salt (NaCl) was added to the beaker until the egg was floating in the middle of the beaker. At this point, the density of the egg and water became equal. Now, the density of the egg could be determined by using the salt water. Each individual group was to find the density of the egg by using three of the five different measurement tools. In this experiment a 50mL graduated cylinder, burette, and 10mL volumetric pipette were used to conduct the experiment. Four tests were done using each of the three measurement tools. To determine the density of the egg using the graduated cylinder, 10mL of the salt water was placed into the graduated cylinder. A beaker was also used. The beaker was weighted and found to have a mass of 52.20g. The salt water from the graduated cylinder was poured into the beaker and weighed again. The mass of the beaker with the salt water subtracted by the mass of the beaker without salt allowed us to find the mass. The mass, 10.15g, was than divided by 10mL to find the Density of 1.02g/mL. This step was repeated three more times but increasing the volume by 10mL each time. The same concept was used again only using a Burette. The Burette was filled with the
