Question

Which of the following is the correct measurement for the volume of liquid shown below? Snapshot of a graduated cylinder partly filled with liquid. The meniscus of the liquid is even with the fifth tick mark between 8 mL and 9 mL. © 2010 FLVS 8.5 mL 8.7 mL 85 mL 87 mL

Answer 1

8.5 mL

Step-by-step explanation:

The meniscus, which is the curvature of the surface of a liquid that is produced in response to the surface of its container, must coincide with the mark of the graduated cylinder in which it is contained, in this case it is 8.5 mL. This measurement should be carried out with the flush mark just at eye level.

Answer 2

The answer is 8.5. The graduated cylinder;s tick mark is between 8mL and 9mL so it can be either  8.7mL or 8.5mL. But from the picture that I have searched which has the same question as yours, it is in the middle of 8 and 9mL. So this means it is 8.5mL.
