The changes in the volume and concentration of solutions are determined using the dilution formula.

What is dilution?

Dilution is the process of preparing a less concentrated solution from.a more concentrated solution.

The dilution formula is as follows:

  • C1V1 = C2V2

Using the dilution formula;

1. Final Volume, V2 = 500 × 3/1 = 1500 mL

2. Final Concentration, C2 = 12 × 50/200 = 3.0 M

3. Initial concentration, C1 = 250 × 0.5/7 = 17.8 M

4. Final volume = 300 × 0.1/0.05 = 600 mL

Volume of water required = 600 - 300 = 300 mL

5. Final volume = 900 mL

Final concentration, C2 = 340 × 0.5/900 = 0.19 M

Therefore, the change in volume and concentration of solutions are determined using the dilution formula.
