. A volumetric flask was used to make the diluted solutions in this experiment. If you accidentally filled the flask above the mark.a. Would the concentration of solution be higher or lower than desired? Explain.

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)

A bacterial stock solution was found to have a density 5.0 x 106 cells. The microbiologist took 1 mL of the stock solution and diluted it to a final volume of 10 mL with the appropriate media. Which of the following statement regarding the dilution is true?

A student performed a serial dilution involving a 1.00 mol dm–3 solution of NaCl. To do this, the student took 10 cm3 of that solution, added it to a 100 cm3 volumetric flask and diluted with water up to 100 cm3 to create dilution #1. The student then took 10 cm3 of dilution #1, added it to a 100 cm3 volumetric flask and diluted with water up to 100 cm3 to create dilution #2. The student repeated this process 3 more times to get dilution #5.Calculate the concentration of dilution #5 in g cm–3.

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?

Determine whether a solution made by dissolving 6 teaspoons of gelatine in 400 mL of apple juice be more dilute or more concentrated. Explain your answer.
