uestion 210.2 pts You have 5.00 mL of 2.26 M potassium bromide solution. If you add water until the total volume reaches 500.0 mL, what will be the molarity of potassium bromide in the resulting solution?

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
