p. 31 Molarity By Dilution (mixing with water. a concentrated solvent) Acids are usually acquired from chemical supply houses in concentrated form. These acids are diluted to the desired concentration by adding water. Since moles of acid before dilution = moles of acid after dilution, and moles of acid : CV then, C1 X V1 = C2 X V2.

Problem 8. Let's return to dilution problems, but work now with molarity expressions instead of percentage concentration expressions. An example: If you add 85 mL of water to 38 mL of 0.6 M glycine solution, what is the concentration of the new solution? Clearly the volume of the new solution is 123 mL.

Also, the number of moles of solute in the dilute solution is equal to the molarity of the dilute solution times the volume of the dilute solution. Since we are really interested in the molarities and volumes we can substitute and use the equation shown in the second line (or third line, depending on your preference for how to show multiplication).
