A chemistry student wants to find the concentration of a hydrochloric acid (HCl) solution. To do this, the student performs a titration experiment with a sodium hydroxide (NaOH) solution of known concentration. The student adds 25 mL of the HCl solution to a flask with an indicator, and then slowly adds the NaOH solution until the indicator changes color. It was found that it took 18.2 mL of the 0.1 M NaOH solution to reach the endpoint. What is the concentration of the HCl solution?
