Each student uses a graduated cylinder to obtain the ethylene glycol volume and a balance to obtain the ethylene glycol mass. Their density values are shown in the table below. a) Determine the average density and the standard deviation in this density data set. You may use your graphic calculator or Excel. Density (g/mL) Density Student I.II (g/mL) 2 1.21 1.30 4 1.01 5 I.13 beaker graduated cylinder b) During the second part of the laboratory activity, the students decide to determine the density of ethylene glycol using a beaker. The results are using the graduated cylinder. Which glassware yielded the more precise measurements?
