Purpose of Experiment: This experiment had three main purposes; the first was to determine the density of a metal cylinder using only a scale and a ruler. The second was to use water displacement to determine the volume of both cylindrical and irregularly shaped pieces of metal, which was then used to calculate the density of the metal. The third and final purpose was to determine the density of a sugar water solution which was then used to discover what the percent of sugar in the solution was. Experimental Procedure: Part One: We began by taking the mass of our metal sample, after that was completed we measured the length and diameter of the cylinder. We then used the information gathered to calculate the density of the metal cylinder. Part Two: In this part we began by massing out both the metal sample and our 25mL graduated cylinder (each separately). Next we placed the metal inside the graduated cylinder and added water to the cylinder until the metal was submerged. We then recorded the volume in the graduated cylinder, after which we massed out the graduated cylinder with the metal and water in it. Then we used the information gathered to find the density of the sample metal.

    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.
