Solution
It seems like there are some missing values in your question. However, I can provide a general step-by-step guide on how to make a 10x dilution to a total volume of 1 ml.
-
First, you need to determine how much of your original sample and how much diluent (usually distilled water or another appropriate solution) you need. For a 10x dilution, you would use 1 part sample and 9 parts diluent. Since the final volume should be 1 ml, this means you would use 0.1 ml (or 100 µl) of your sample and 0.9 ml (or 900 µl) of your diluent.
-
Take an Eppendorf tube and using a micropipette, transfer 100 µl of your 10x sample solution into the tube.
-
Next, using a different micropipette to avoid cross-contamination, add 900 µl of your diluent to the Eppendorf tube.
-
Cap the tube and mix the solution gently by inverting the tube several times. This ensures that the sample and the diluent are thoroughly mixed together.
-
Your 10x dilution is now ready. The final volume in the tube should be 1 ml.
The error introduced by the micropipettes depends on their repeatability. If the repeatability is ±1%, this means that the volume dispensed by the micropipette can vary by up to 1% each time. This could introduce a combined error of up to 2% in your final dilution (1% from the sample and 1% from the diluent).

To get 2 mL of 0.625 M solution, take 0.5 mL of the second diluted solution (0.625 M) and add it to 1.5 mL of solvent. Detailed Procedure First Dilution: Take 1 mL of the 10.01 M stock solution and add 3 mL of solvent (water) in Tube 1. Mix thoroughly to get 4 mL of 2.5025 M solution. Second Dilution: Take 1 mL of the 2.5025 M solution from Tube 1 and add 3 mL of solvent in Tube 2. Mix thoroughly to get 4 mL of approximately 0.625 M solution. Final Preparation: Take 0.5 mL of the 0.625 M solution from Tube 2 and add 1.5 mL of solvent in Tube 3. Mix thoroughly to get 2 mL of 0.625 M solution.
Your solution is 10000 times more dilute than the original bacterial sample (ie 1x10-4). Your take 0.5ml of this solution and add it to 4.5ml saline.
