Let's solve each of the graduated cylinder readings step by step. The key to reading a graduated cylinder correctly is to look at the
bottom of the meniscus (the curved surface of the liquid) and read the volume at that level.
We’ll go through each one:
---
a)
- The markings go from 50 to 60 mL.
- There are 10 small divisions between 50 and 60 → each division =
1 mL.
- The meniscus is at the
58 mL mark.
✔ Answer: 58 mL
---
b)
- Markings go from 3 to 4 mL.
- There are 10 small divisions between 3 and 4 → each =
0.1 mL.
- The meniscus is at
3.7 mL (just below the 3.8 line).
✔ Answer: 3.7 mL
---
c)
- Markings go from 20 to 30 mL.
- 10 divisions → each =
1 mL.
- Meniscus is just above 20 → at
22 mL.
✔ Answer: 22 mL
---
d)
- Markings from 10 to 25 mL in increments of 5.
- Between 15 and 20, there are 5 divisions → each =
1 mL.
- Meniscus is at
19 mL (just below 20).
✔ Answer: 19 mL
---
e)
- Markings from 65 to 80 mL.
- 10 divisions between 70 and 80 → each =
1 mL.
- Meniscus is at
76 mL.
✔ Answer: 76 mL
---
f)
- Markings from 2 to 5 mL.
- 10 divisions between 2 and 3 → each =
0.1 mL.
- Meniscus is at
4.3 mL.
✔ Answer: 4.3 mL
---
g)
- Markings from 10 to 40 mL.
- 10 divisions between 30 and 40 → each =
1 mL.
- Meniscus is at
33 mL.
✔ Answer: 33 mL
---
h)
- Markings from 1 to 4 mL.
- 10 divisions between 3 and 4 → each =
0.1 mL.
- Meniscus is at
3.4 mL.
✔ Answer: 3.4 mL
---
i)
- Markings from 40 to 50 mL.
- 10 divisions → each =
1 mL.
- Meniscus is at
46 mL.
✔ Answer: 46 mL
---
✔ Final Answers:
a)
58 mL
b)
3.7 mL
c)
22 mL
d)
19 mL
e)
76 mL
f)
4.3 mL
g)
33 mL
h)
3.4 mL
i)
46 mL

Tip: Always read the
bottom of the meniscus and estimate to the nearest
0.1 mL if possible. Make sure your eye is level with the liquid to avoid parallax error.
