Suppose you are working with a NaOH stock solution but you need a solution with a lower concentration for your experiment. Calculate the volume of the 1.475 M stock NaOH solution needed to prepare 250.0 mL of 0.1374 M dilute NaOH solution.

Explanation:

In this case, we have a dilution problem. We have to remember that in the dilution procedure we go from a solution with higher concentration to a solution with lesser concentration. Therefore we have to start with the dilution equation:

Now we can identify the variables:

If we plug all the values into the equation:

And we solve for :
