Step 2:
: Understand the Measurement Challenge

The goal is to accurately measure 1.25 mL using a 3 mL syringe. This requires careful observation and precise measurement techniques.

Step 3:
: Visualize the Syringe Markings

\frac{1}{2} \text{ mL increments}
A typical 3 mL syringe will have graduations that typically represent:

Step 4:
: Locate the Precise Measurement

- Align the plunger with the $$1.25 \text{ mL}$$ point
To measure 1.25 mL, you'll need to:

Step 5:
: Measurement Technique

- Ensure the bottom of the plunger's meniscus aligns precisely with the $$1.25 \text{ mL}$$ mark
- Draw liquid slowly into the syringe - Hold the syringe at eye level

Final Answer

Carefully draw the liquid into the 3 mL syringe, stopping exactly at the 1.25 \text{ mL} graduation mark by aligning the bottom of the plunger's meniscus with this point.
