These equipment are, beaker, a graduated cylinder, and volumetric pipet. The second objective is to find out which equipment is the most precise and accurate to use in finding the density of Coke and diet Coke. Also, a part of this experiment is to find the uncertainty of a specific equipment and what is the cause of the uncertainty. Every measuring equipment has an uncertainty range associated with it. However some measuring devices have greater uncertainty than other, and of course, the more expensive an equipmentis the more accurate and precise the results are. Error can and will occur while working on an experiment, it could be a random or systematic error. When a random error occurs we can detect it because unpredictable changes occur in the experiment. These changes may occur in the measuring equipment or in the environmental conditions. We can minimize the effects of random error by taking more data. Random error can be reduced by averaging over a large number of observations. In systematic error however, we can pinpoint the exact cause of the error and fix the problem. This is doing by finding the average, the mean, and the standard deviation of a given data.3Part IData/Results/Calculations:Accuracy and Precision of the three Glassware: Instrument Uncertainty Average VolumeStandard DeviationPrecision (good, fair, poor)True Value Accuracy (good, fair, poor)Beaker +/- 1mL 51.7mL 3.282 poor 50.0mL fairGraduated Cylinder+/- 0.1mL 10.10mL 0.6608 fair 10.00mL goodPipet +/- 0.2 10.03mL 0.01183 good 10.00mL goodI used a 50mL beaker, and filled with water then weighed the mass of both beaker and water.
