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

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
