Densities of Liquids and Solids Results and Discussion: The purpose of this lab was to determine the densities of an unknown solid and liquid as accurately and precisely as possible. To do this, the mass and volume of the solid and liquid were measured. Then, their densities were calculated using the formula, Density = Mass / Volume. The mass of the solid was measured using an electronic balance; its volume was determined by placing the solid into a graduated cylinder filled with 10 mL of water and seeing how much the

water rose. The mass of the liquid was made by measuring out 10 mL of the liquid and then weighing its mass using the electronic balance. Initially, two trials were performed on the unknown solid. The data and calculated results were tabulated (Table 1). Table 1: Mass, Volume, and Density of Unknown Solid Trial Mass (g) Volume (mL) Density (g/mL) 1 6.976 1.3 5.4 2 6.968 1.2 5.8 The density was calculated by the following: D= M/V= (6.976g)/(1.3mL)=5.4g/mL

    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.
