Purpose To determine the identity of unknown samples of liquids and solids through calculations of their densities. Results and Discussion Experimental procedures were practiced using a sample of distilled water. A sample of the water was taken using a pasteur pipette. A beaker was measured before and after the addition of the sample using an electronic balance. The density of water was then calculated. Mass of Water – 9.950 Grams Volume of Water – 10.0 mL Density = Mass = 9.950 grams = 0.995 g/mL Volume 10.0 mL The accepted density for water is 1.0 g/mL. The percent error was thus calculated to quantify the accuracy of the results. Percent error = accepted value – measured value x 100 = 1.0 – 0.995 x 100 = 0.5% accepted value 1.0 The experimental procedures were then repeated using a sample of unknown liquid #3. This procedure was repeated three times.

### What students are saying

• 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.
