sentences. 3. Virtual Lab Questions a. A student prepares a solution of hydrochloric acid that is approximately 0.1 M and wishes to determine its exact concentration. A 25.00 mL portion of the HCI solution is transferred to a flask, and after a few drops of indicator are added, the HCI solution is titrated with 0.07575 M NaOH solution. The titration requires exactly 38.92 mL of the standard NaOH solution to reach the end point. What is the molarity of the HCI solution? b. It takes 46.22 mL of a 1.021 M NaOH solution to neutralize a solution of 4.4567 g of an unknown monoprotic acid in 80.00 mL of water. Calculate the molecular weight of the acid. 4(D) 5
