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
i don,t know so just answer mine
Yes it would be a physical change.
