1. what volume is shown in the graduated cylinder below? 20.4 ml 24.0 ml 28 ml 30 ml
Answer
Explanation:
Step1: Identify scale interval
The scale on the graduated - cylinder has markings from 20 mL to 40 mL. There are 10 intervals between 20 mL and 40 mL. So the value of each interval is $\frac{40 - 20}{10}=2$ mL.
Step2: Determine the meniscus position
The meniscus (the bottom of the liquid curve) 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:
24.0 mL
