In the lab, Stock bottles of concentrated solutions can be diluted to make solutions for use with a lab. The dilution formula is C1V1=C2V2; here C= concentration and V= volume, the 1 = initial and 2= final. Use this formula to determine what volume of a 12M Stock solution will be used to make 500mL of a 3M solution. Then determine the volume of water you will add to the calculated amount of Stock solution to dilute it to the proper concentration and volume.
