**Apply the formula to find the concentration of solutions.**- Find the concentration of a solution where 0.7 mol NaOH is dissolved into 120 mL of water.
- Find the concentration of another solution where 0.45 mol HCl is dissolved into 95 mL of water.
- Find the concentration of the solution that will be made if 32 grams of NaOH pellets are weighed out and dissolved in a container with 200 mL water.

**Apply the formula to find changing concentration and volume of solutions.**- Find the molarity of this solution.
- 45 mL extra water is added to dilute this solution. Find the new concentration of this solution.
- This solution is diluted down further and the concentration is measured to be 0.55 M. What must the new volume of the solution be?
- In a separate experiment, a 50 mL solution of .450 M MgCl
_{2}was mixed with 20 mL of 0.3 M AlCl_{3}. Find the concentration of all the ions present in this combined mixture.
