Question

measuring volume
8.
9.
10.

Explanation:

Step1: Determine scale - interval of first cylinder

The first cylinder has markings from 40 - 50 mL with 10 sub - divisions. So the scale - interval is $\frac{50 - 40}{10}=1$ mL. The meniscus is at 45 mL.

Step2: Determine scale - interval of second cylinder

The second cylinder has markings from 3 - 4 mL with 10 sub - divisions. So the scale - interval is $\frac{4 - 3}{10}=0.1$ mL. The meniscus is at 3.5 mL.

Step3: Determine scale - interval of third cylinder

The third cylinder has markings from 25 - 30 mL with 10 sub - divisions. So the scale - interval is $\frac{30 - 25}{10}=0.5$ mL. The meniscus is at 28 mL.

Answer:

1. 45 mL
2. 3.5 mL
3. 28 mL
