Answer:

The answer to your question is Final concentration = 0.023 M

Explanation:

Data

Volume 1 = 5 ml

Concentration 1 = 2.26 M

Volume 2 = 500 ml

Concentration 2 = ?

Process

1.- To solve this problem use the dilution formula

   Concentration 1 x Volume 1 = Concentration 2 x Volume 2

- Solve for Concentration 2

     Concentration 2 = [Concentration 1 x Volume 1] / Volume 2

- Substitution

      Concentration 2 = [5 x 2.26] / 500

- Simplification

      Concentration 2 = 11.3 / 500

- Result

      Concentration 2 = 0.023 M
