Determine the volume of fluid in the graduated cylinder shown. 8.135 mL 8.15 mL 8.13 mL 8.23 mL

Explanation:

The picture with the graduated cylinder is missing.

See attached the picture with a graduated cylinder showing a volume of fluid between 8 and 9 mL, which is good to explain you how to solve this kind of problems.

First, you must know that the lecture is read where the meniscus is, the curve, of the fluid is. Since the curve is upward, you must read the mark that coincides with the bottom of the meniscus.

Second, determine what the marks mean. Count: there are 9 lines between 8 and 9; that is 10 divisions. If 8 is the mark for 8 mL and 9 is the mark for 9 mL, then each line is [ 9ml - 8ml] / 10divisions  = 1 mL / 10 = 0.1 mL

Thus, the meniscus is between the marks of 8.1mL and 8.2mL.

Third, approximate: you can appreciate that the mark is, approximately, in the midpoint between 8.1mL and 8.2mLm, then the measure is
