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 19.0oC. The density of waterat 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 What is the true mass of water delivered in A?
