the diagram below shows a portion of a graduated cylinder. what is the volume of the liquid in this…

Explanation:

Step1: Identify the scale interval

The scale on the graduated - cylinder has values from 20 to 30 mL with 5 intervals. So, the interval between each small division is $\frac{30 - 20}{5}=2$ mL.

Step2: Locate the meniscus

The meniscus (the curved surface of the liquid) is at the 2nd mark above 20 mL.

Step3: Calculate the volume

Since each mark is 2 mL and it is 2 marks above 20 mL, the volume is $20+2\times2 = 24$ mL.

Answer:

B. 24 mL
