Worksheet: The Dilution Equation

In this worksheet, we will practice calculating the concentration after a solution is diluted or the solvent volume needed to reach a target concentration.

Q1:

A solution is prepared by mixing 25.0 mL of 0.100 M aqueous K C l with 50.0 mL of 0.0200 M aqueous K C l . Calculate the concentration of K C l in this solution.

Q2:

What does not change when a solution of sodium chloride is diluted from 1.0 L to 1.8 L?

  • AThe total volume
  • BThe concentration of the ions
  • CThe average distance between ions
  • DThe solubility of sodium chloride
  • EThe amount of solvent
