If you add 1.0 ml of a colored solution (Stock) to 4.0 ml of water in a test tube, what is the dilution ratio, of the colored solution to the final volume?

You have prepared a 2 M stock solution of an analyte you will be diluting to prepare your standard solutions.  What volume (in mL) will you need to add and dilute in a 250 mL volumetric flask to achieve a final concentration of 0.06 M?  Answer to 1 decimal place (Hint: C1V1=C2V2)

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.

What is the dilution when we add 3 ml of stock to 27 ml of water?

If 20 mL of a 2% (w/v) solution are diluted with water to 8 pints, what is the ratio strength (w/v) of thedilution?

If you have a Bradford reagent that you have to dilute 1:4. After dilution the final volume should be 20ml, how much of the Bradford reagent would you use to make this final volume (diluted solution)?
