Chemistry Pre-Lab—Density of an Egg 14/09/2005 16:32:00 Objective:  To determine the densities of eggs that vary in freshness and learn to  use four types of volumetric glassware as well as a balance.  Introduction:  Maria is trying to verify the freshness of her eggs to see whether  they meet her standard. By measuring the density of the egg, one can determine the  degree of freshness.  Materials:  top loading balance: +0.001 g 10 mL graduated cylinder +0.1 mL 10 mL volumetric flask +0.01 mL 10 mL volumetric pipet +0.01 mL 25 mL buret +0.01 mL Procedure:  Prepare a salt solution in which the egg is just able to float. Obtain  mass and volume measurements by using a balance to measure mass and a plethora  of devices for the volume. From this, you will calculate the density of the salt solution as  well as the density of the egg (indirectly). Then you will compare the densities of fresh  and not so fresh eggs.  In proceeding with this experiment, one must be aware of the precision and
