Question

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. For example, in the first cylinder with markings 10, 20, 30, etc., the interval is 10 ml.

Step2: Locate the meniscus

The reading is taken at the bottom of the meniscus (the curved surface of the liquid).
For the first cylinder: The meniscus is at the 30 - ml mark.
For the second cylinder: The interval is 10 ml and the meniscus is at 100 ml.
For the third cylinder: The interval is 0.2 ml and the meniscus is at 1.6 ml.
For the fourth cylinder: The interval is 1 ml and the meniscus is at 35 ml.
For the fifth cylinder: The interval is 0.2 ml and the meniscus is at 1.2 ml.
For the sixth cylinder: The interval is 0.2 ml and the meniscus is at 13.8 ml.
For the seventh cylinder: The interval is 2 ml and the meniscus is at 78 ml.
For the eighth cylinder: The interval is 2 ml and the meniscus is at 220 ml.
For the ninth cylinder: The interval is 0.2 ml and the meniscus is at 7.6 ml.
For the tenth cylinder: The interval is 1 ml and the meniscus is at 55 ml.
For the eleventh cylinder: The interval is 0.2 ml and the meniscus is at 5.6 ml.
For the twelfth cylinder: The interval is 0.2 ml and the meniscus is at 18.4 ml.
