Purpose: The purpose of this lab is to learn how to properly use the top-loading balance, analytical balance, buret, and pipet to correctly evaluate mass, volume, and density. Procedure: Please see pgs. 4 and 5 of General Chemistry Laboratory Experiments, Volume 1 by Judith Casey & Robert Tatz, Hayden McNeil, 2008-2009 Report Form: See attached report form and sample calculations sheet. Report Questions: 1. The mass of the crucible cover was obtained through the use of two different methods in the experiment. One value was found through simple difference between combined mass and crucible mass. The other value was found through measuring the cover directly with the balance. In the data collected, from part A of the experiment, the average values were the same for both methods. In turn, the average deviations were the same for both methods. This is because the top-loading balance was only accurate to the hundredth place, which doesn't leave much room for inaccuracy. Thus, the masses were all the same within ±0.01, allowing for an average deviation to be 0.00 for all values. In part B, where the analytical balances were used,

    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.
