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:

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
