Conclusions and Recommendation : In this experiment, we found out that the diffusion coefficient varies from one compound to another .because some compounds are more volatile than others at certain temperatures and pressures. We observed that the molecular diffusion of gases is a very slow process, the largest value of D ab was 0.3172cm 2 /sec for acetone. One might recommend the use an electronic microscope that monitors the change in the height of the interface and record it instead of the human eye for a better accuracy if such a device exists.

    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.
