EXAMPLE Making Solutions:

How would you make 500 mL of 1.50 M HCl from 12.0 M HCl?


This problem involves the dilution of a more concentrated solution to form a more dilute solution. We can therefore use the dilution problem equation derived above to calculate the volume of concentrated HCl necessary for making the dilute solution.


MC = 12.0 M     VC = ?     MD = 1.50 M     VD = 500 mL


Carefully add 62.5 mL of 12.0 M HCl to a 500-mL volumetric flask. Add water to the flask until the total volume reaches the 500-mL mark on the flask.
