Explanation:

Step1: Determine the scale of the graduated cylinder

The graduated cylinder has markings. Each major division (e.g., from 20 mL to 30 mL) is 10 mL. The number of minor divisions between 20 mL and 30 mL is 10. So the scale of each minor division is $\frac{10}{10}=1$ mL.

Step2: Read the bottom of the meniscus

The bottom of the meniscus (the curved surface of the liquid) is at 23 mL.

Answer:

23 mL
