Pinkey Rahman(pr59889) BIO 205L 1) For 60ml, error= 1.1% For 4-ml, error= 0.75% 2) a) 0.28g b) 0.56g 3) a) The measurements are so small that the percent error in weighing would surpass any miscalculation due to not calibrating. SO recalibration would take up valuable time, and may not even have an impact on the final results of the experiment. b) A top-loading balance could be useful but an analytical balance would be preferred because they are made to weigh to the fourth place or one tenth of a milligram. Therefore give a more accurate measurement. 4) The different measuring devices are used to demonstrate the varying degrees of accuracy of each device Automatic pipettes are equipped with pipette pumps that are made to measure small volumes of liquid. And the graduated cylinders are meant to be used for measuring larger amounts of solution. 5) In order to determine the density, both the exact mass and volume must be determined.

    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.
