A 5.0mL sample of a stock solution of concentrated HNO3, a strong acid, is diluted with distilled water to prepare 100.0mL of its dilute solution. A 10.0 mL sample of this dilute solution is then taken, and a pellet of sodium hydroxide NaOH, with a mass of 250 mg is added to it. This pellet completely neutralizes the dilute acid solution. Calculate the molarity of the original stock solution of concentrated HNO3.
