- Mola and Rity were tasked to analyze the acidity of a 10.0-mL fermented milk sample diluted with water in a 250-mL volumetric flask. Mola obtained a 15.0-mL aliquot of this solution, diluted it to 50.0 mL, and then titrated this diluted sample. Titration data were given to Rity and she found out that the 50.0-mL diluted sample contains 0.21 mmol of lactic acid.

She takes 160 mg of your benzoic acid and dissolves it in just enough water so the solution exactly fills a 250 mL volumetric flask. Given that the acid dissociation constant of benzoic acid Ka = 6.3 x 10-5, calculate the pH of her resulting solution.John wanted to determine the protein content of his blood. To do so, he obtained 1.00 mL of blood, and diluted it to 10.00 mL. From that solution, he subjected 1.00 mL to Kjeldahl analysis. After digestion, the liberated NH3 was distilled in a flask containing exactly 25.00 mL of 0.0150 M H3BO3. Titration requires 5.85 mL of standard 0.0150 M NaOH to reach the desired endpoint. If a typical blood sample contains 15.45 g N per 100 g protein, calculate the protein content (in g/mL) in the sample of John’s blood.
