100%

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^oC. 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 Burrette Reading , mL	10.05	20.04	30.08	40.07	49.98
