I) Purpose : The purpose of this lab experiment is to isolate each component of a mixture and to determine the percent by mass of each present. II) Procedure : Casey, J. and R. Tatz (2008). Measurements of Mass and Volume; Density. General Chemistry Laboratory Experiments , Hayden McNeil. Vol.1: 11-20. III) Data: (See attached Report Form) IV) Calculations : Percent composition of organic solid “X” = × % Percent component Mass of componentTotal Mass of sample 100 = . . × % Percent Composition 0 1725g0 5209g 100 = . × % Percent composition 0 3312 100 = . % Percent Composition 33 12 V) Error Analysis/Conclusion : There were several possible sources for error in the procedure of this experiment. In Part B of the experiment, the organic component may not have been completely separated from the mixture, and as a result could cause the percent composition calculations to be inaccurate.

    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.
