Let’s figure out what the measurement is on this graduated cylinder.
First, look at the numbers: 1, 2, and 3. These are probably milliliters (mL), since that’s common for small liquid measurements in science class.
Between each whole number — like between 2 and 3 — there are smaller lines. Let’s count how many spaces there are between 2 and 3.
From 2 to 3, there are 10 small lines. That means each small line represents 0.1 mL (because 1 divided by 10 = 0.1).
Now, look at where the bottom of the curved surface of the liquid (called the meniscus) is. It’s right at the second small line above the 2.
So:
- Start at 2.0
- Add 0.1 for the first line → 2.1
- Add another 0.1 for the second line → 2.2
That means the volume is 2.2 mL.
Double-check: The meniscus is clearly aligned with the second mark after 2, not halfway or closer to 3. So yes, 2.2 is correct.
Final Answer:
2.2
