5ml

To estimate 5 mL of liquid using a test tube with a capacity of 23 mL, you can follow the steps below:

1. Fill the test tube with water from a calibrated or known volume container until it reaches close to the 23 mL mark. Ensure you are holding the test tube at eye level to accurately gauge the volume.

2. Take note of the water level in the test tube. Let's assume it reads 21 mL.

3. Carefully pour out some water until the water level is 2 mL below the initial reading. In this case, pour out approximately 2 mL of water to reach 19 mL.

4. Now, you have an estimate of 19 mL in the test tube. Since you need approximately 5 mL, deduct 5 mL from the current volume (19 mL - 5 mL = 14 mL).

5. Pour out the excess water until the water level reaches approximately 14 mL. Remember to pour slowly and carefully, especially when approaching the desired volume.

By following these steps, you can estimate an approximate volume of 5 mL in the test tube with a capacity of 23 mL.
