Making Dilutions Worksheet

Remember that you can change the concentration of a solution by adding more solvent.

While you cannot increase the concentration of a solution in this manner, you can create a more

dilute solution by increasing the amount of solvent. You can determine the amount of a solution

needed to dilute by using the following:

x V

= M

x V

Where M = molarity and V = volume. M

and V

are the initial solutions molarity and volume, while

and V

are the final solutions molarity and volume.

Use the formula and information above to solve the following problems. Show your work and

watch labels. The first three problems are questions regarding molarity and the others involve the

dilutions formula above.

1. Determine the number of grams of NaHCO

that are in one liter of a 2.1 M solution

2. Determine the number of grams of NaNO

that are present in 500 mL of a 1.0 M solution.

3. Determine the number of grams of CCl

in 450 mL of a 3.2 M solution.

4. You have to make 500 mL of a 0.50 M BaCl

. You have 2.0 M barium chloride solution

available. Determine how to make the needed dilution.

5. You need to make 300 mL of a 0.40 M solution of sodium chloride. The only available

solution is 1.0 M. Determine how to make the needed dilution.
