These two questions seem to contradict, please explain:
Q: An organic chemist wanted to deliver 15.6ml of a liquid in an experiment. Which should she employ?
graduated cylinder
buret
pipet
volumetric flask
condenser
ans: a pipet is calibrated to deliver a specific volume of liquid when filled to the mark and allowed to drain. The buret will deliver known volumes of solution, but during a titration.
Q: A student wanted to measure exactly 12.3ml of a 0.2M NaOH solution. Which should she use?
transfer pipet
buret
soxhlet extractor
graduated cylinder
volumetric flask
Ans: since the student wanted to measure exactly 12.3ml, an odd vol, a buret would be best. Pipets allow transfer of accurately known volumes from one container to another. The precision that you get from a buret is much greater than a pipet.
