Which is correct regarding the relative accuracies of a volume of about 12 mL?
Which of the following statements is correct regarding the relative accuracies of a volume of about 12 mL determined by weighing the contained mass and by direct measurement with a 25 mL graduated cylinder?
a. Measurement with a 25 mL graduated cylinder can easily determine the volume to one part in 10,000 whereas measuring the contained mass of water can only determine the volume to one part in 1,000 and therefore the graduated cylinder provides the more accurate determination.
b. Measurement with a 25 mL graduated cylinder can only determine the volume to one part in 1,000 whereas measuring the contained mass of water also determines the volume to one part in 1,000 so that either measurement provides the same level of accuracy.
c. Measurement with a 25 mL graduated cylinder can only determine the volume to one part in 100 whereas measuring the contained mass of water can only determine the volume to one part in 10 and therefore the graduated cylinder provides the more accurate determination.
d. Measurement with a 25 mL graduated cylinder can determine the volume to one part in 100 whereas measuring the contained mass of water can easily determine the volume to one part in 10,000 and therefore weighing the contained mass provides the more accurate determination.
e. None of the above.
