12. which of the following correctly measures the volume (in ml) depicted by the image below? 18 ml 18.30 ml 18.300 ml 18.3 ml
Answer
Explanation:
Step1: Identify scale intervals
The scale ranges from 15 mL to 20 mL with 5 - equal intervals. So each interval is $\frac{20 - 15}{5}=1$ mL.
Step2: Determine the meniscus position
The meniscus (the curved - surface of the liquid) is at the 3rd mark above 15 mL. So the volume is $15+3 = 18$ mL.
Answer:
18 mL
