A volumetric pipette was used to transfer 10.00 mL of HCI solution into a 125 mL Erlenmeyer flask. A couple of drops of phenolphthalein to the HCI solution was alsoadded to the flask.The standardized NaOH solution titrated into the flask was 0.9980 M. When the endpoint was reached, 15.50 mL was dispensed from the buret. What is the molarity of the HCl acid?
