Solution Concentration

• The following formula can be used in dilution calculations:

M1V1 = M2V2

• A concentrated stock solution is much easier to prepare and then dilute rather than preparing a dilute solution directly. Concentrated sulfuric acid is 18.0M. What volume would be needed to prepare 250.mL of a 1.50M solution?

• V1 = M2V2 / M1

• V1 = 1.50 M x 250. mL / 18.0 M

• V1 = 20.8 mL
