tools
x10^y

Explanation:

Step1: Identify the scale interval

The graduated - cylinder has markings from 20 mL to 30 mL, 30 mL to 40 mL, etc. The interval between each major marking is 10 mL, and there are 10 smaller intervals between each major marking. So, the scale interval is 1 mL.

Step2: Read the volume at the meniscus

The meniscus (the curved surface of the liquid) is at the 22 - mL mark.

Step3: Determine significant figures

Since the measurement is made to the nearest 1 mL, the volume 22 mL has two significant figures.

Answer:

22
