Brandon Smith Chem 107-522 2/7/08 Summary The procedure of this experiment was fairly simple. We found the mass of a clean beaker, and then used a pipette to add 5 ml of water until we had 25 ml, reweighing the beaker after each 5 ml addition of water. We later used these results to find the average volume of the pipette. We then repeated the process using acetone. With these results combined with the average volume of the pipette we calculated from the first part, we were able to calculate the density of acetone in grams per milliliter. We were able to see from these experiments that mass and volume are conserved. For the next part of the experiment we found the mass of a graduated cylinder and again added 5 ml of water, reading both the volume and mass to see if it was conserved. In the last part of the experiment, we used our pipette to add 5 ml of water and 5 ml of acetone to see if mass and volume were conserved in the mixture of liquids. As expected, it was.

    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.
