experimental methods and on the data you obtained. You should discuss any experimental error that was introduced and comment on alternative ways your experiments could have been run. While reviewing my date for the experiment, I believe the most accurate density I calculated would be the buret measurements due to the buret being the only one from the three measurement methods to increase by .1 mL. Unlike the graduated cylinder and the beaker the burets densities weren’t as roun ded up. My partner and I each took different responsibilities. One of us would sometimes measure the item on the scale while the other gathered what the other supplies to continue the experiment. One experimental error might be the fact that we weren’t abl e to dry out the measuring items before re-weighing like in the grad cylinder and the beaker. For the buret we would add water to it so all three experiments would have the same initial volume to make it a little less confusing and a bit more accurate. 1. Which measurement method(s) gave you the most and the least precise measurements (similar numbers for each reading)? Why do those methods lead to more/less precise readings? The buret gave the most precise measurements because it increases by 0.1mL making it more accurate unlike the beaker which increased by 10mL at a time.

    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.
