Part B (Comparison of glassware syrological pipette)
Temperature: -22.6
Density: -0.997632 g/cm3
Table B:
Experimental volume of water (from pipette)
20.00 ml

Mass of water transferred from the pipette
19.57 ml

1. Volume =
=
=19.61 g/cm3
2. % error =
=
=1.988781%
Part C. Comparison of glassware: graduated cylinder
Temperature: – 22.6
Density: -0.997655 g/cm3
Experimental volume of water (from graduated cylinder)
20.00 ml

Mass of water transferred from the graduated cylinder
20.25 ml

1. Volume =
=
=20.30 g/cm3
2. % error =
=
= -1.477833%
Part D: Comparison of glassware: Beaker
Temperature: -22.7
Density: -0.997608 g/cm3
Experimental volume of water (from the beaker)
20.00 ml

Mass of water transferred from the beaker
19.40 ml

1. Volume =
=
= 19.46 g/cm3
1. % error =
=
= 2.774923%
Conclusion
1. The order of glassware from the least to the most accurate is D, B and C respectively. The reason for this order is because of the percentage error; the closer the percentage error to zero, the more the accurate is the glassware.
1. The glassware used in part C is the most accurate. The reason behind this is because the percentage error is more close to zero than others in B and D, hence precise.
