A student performed a titration in which aqueous NaOH (concentration = 0.1000 mol/L) was added via burette to a 25.00 mL aliquot of aqueous HCl in an Erlenmeyer flask. Endpoint was reached after the student added 24.01 mL of sodium hydroxide. What concentration of chloride ion is present in the flask once endpoint was reached? Report your answer to three significant figures. Calculate your answer in units of mol/L, but do not input units when submitting your response. Concentration of chloride ion in flask at endpoint = ? mol/L
