1.07 Accuracy and Precision Lab By: Heather Owens
Data Part I: : Density of Unknown Liquid Trial 1 Trial 2 Trial 3 Mass of Empty 10 mL graduated cylinder (grams) 26 25 25 Volume of liquid (milliliters) 8.4 8.6 8.7 Mass of graduated cylinder and liquid 36 36 36 Part II: Density of Irregular-Shaped Solid Trial 1 Trial 2 Trial 3 Mass of solid (grams) 42.817 41.226 40.875 Volume of water (milliliters) 50 51 50 Volume of water and solid (milliliters) 55 56 55 Part III: Density of Regular-Shaped Solid Trial 1 Trial 2 Trial 3 Mass of solid (grams) 26 26.5 27.5 Length of solid (centimeters) 5.3 5 4.5 Width of solid (centimeters) 3 4 3.5
Calculations Part I: Density of Unknown Liquid Calculate the mass of the liquid for each trial. (Subtract the mass of the empty graduated cylinder from the mass of the graduated cylinder with liquid.) Trial 1 36 – 26 = 10 grams Trial 2 36 – 25 = 11 grams Trial 3 36 – 25 = 11 grams Calculate the density of the unknown liquid for each trial. (Divide the mass of the liquid calculated above by the volume of the liquid.) Trial 1: 10 / 8.4 = 1.2 Trial 2: 11 / 8.6 = 1.3 Trial 3: 11 / 8.7 = 1.3

### 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.
