A student places 20.00mL of .1005 M HCl in a flask and adds a few drops of phenolphthalein. She adds a NaOH solution of unknown molarity to a buret and records the initial reading as 1.50 mL. She adds the NaOH solution from the buret ro rhe HCl solution until a pale pink color is obtained and records the final buret reading as 22.00 mL. What is the molarity of the NaOH solution? Show your calculations.
