Exp. #1: Floating Egg Problem 01 January 2008 Introduction: The purpose of this experiment is to calculate the density of the solution needed to float an egg in water. Also, to determine in what way various volumetric glassware’s affects density and accuracy of volume. Useful equations used in this experiment were both density and standard deviation. Procedure: Part 1: 1) Obtain 1500 mL of deionized water in a container 2) Add 200 g of NaCl slowly, then stir 3) Put egg in salt water 4) Keep adding NaCl until egg floats, adding 200 g of NaCl at a time Part 2: 1) Add 25 mL of solution in flask 2) Weigh Erlenmeyer flask empty, and then weigh with the solution. 3) Do this for each volumetric glassware (Buret, Mohr Pipette, Volumetric Pipette, Volumetric Flask) Data:
