1. explain the precision and accuracy of results given in file uploaded ( file name: Lab report) and whether water, glycerol volume, density, or pipette size is important. .2. how the experiment went in lab, and how it might have affected your results.Some of the reason that might have affected as follows-The time was constrained so couldn’t finish the entire experiment.Due to viscosity of glycerol, while pipetting in and out, lot of bubbles were formed as result correct volume of glycerol couldn’t be pipetted.-the numbers on weighing machine kept fluctuating a lot.
