All work should be shown with correct sig figs and units in notebook pages for the volumetric analysis project. 1a. A student weighed out a 0.215 g sample of KHP (MW 204.2 g/mol), dissolved it in 20 mL distilled water, and added phenolphthalein. The student titrated the sample with a NaOH solution and found that it took 12.40 mL to reach the endpoint. Calculate the molarity of the NaOH solution. 1b. The student then used the above NaOH solution to titrate 15.0 mL of an acetic acid solution (HC₂H₂O2). Calculate the molarity of the acetic acid solution knowing that 27.15 mL of the NaOH solution were required to reach the end point. 2. Later the student used the above NaOH solution to titrate 20.0 mL of a sulfuric acid solution (H₂SO4). Calculate the molarity of the sulfuric acid solution knowing that 33.45 mL of the NaOH solution were required to reach the end point.
