what is the reading in milliliters for each graduated cylinder?

Explanation:

Step1: Identify scale intervals

For each graduated - cylinder, first determine the value of each scale interval.

Step2: Locate the meniscus

Find the bottom of the curved surface (meniscus) of the liquid in the graduated - cylinder.

Step3: Read the volume

Read the value on the graduated - cylinder at the level of the meniscus.

1. First row, first cylinder: The scale interval is 0.2 mL. The meniscus is at 23.2 mL.
2. First row, second cylinder: The scale interval is 0.2 mL. The meniscus is at 14.0 mL.
3. First row, third cylinder: The scale interval is 1 mL. The meniscus is at 56.0 mL.
4. First row, fourth cylinder: The scale interval is 1 mL. The meniscus is at 40.0 mL.
5. Second row, first cylinder: The scale interval is 0.2 mL. The meniscus is at 6.6 mL.
6. Second row, second cylinder: The scale interval is 0.2 mL. The meniscus is at 1.6 mL.
7. Second row, third cylinder: The scale interval is 0.2 mL. The meniscus is at 22.6 mL.
8. Second row, fourth cylinder: The scale interval is 0.1 mL. The meniscus is at 1.9 mL.
9. Third row, first cylinder: The scale interval is 1 mL. The meniscus is at 30.0 mL.
10. Third row, second cylinder: The scale interval is 2 mL. The meniscus is at 80.0 mL.
11. Third row, third cylinder: The scale interval is 2 mL. The meniscus is at 144.0 mL.
12. Third row, fourth cylinder: The scale interval is 1 mL. The meniscus is at 60.0 mL.
