- One student calibrated a 50-ml burette by using the mass of water delivered. The student used an analytical balance which was previously calibrated by STEEL (density = 7.8 g/mL). During calibration, the temperature of water was found to be 19.0.C. The density of water at this temperature is 0.9984 g/ml The results of the calibration by the student is shown in the table below: A B C D E Apparent burette reading,mL 10.05 20.04 30.08 40.07 49.98 Weight H2O delivered, g 10.03 20.09 30.05 40.02 49.83 Note: All masses in mentioned in this section are understood to be in grams and all volumes mentioned are understood to be in milliliters. 35.
