Once upon a time, Tricia and her friend Jillian are doing titration to assess the molarity of the sample's total acid content. Using the pH measurements to report acidity, they were ordered to study a clear aqueous solution of an unknown monoprotic acid. They decided to use two methods of experiments to gather essential data for their Chemistry Class. The first method is through a pH strip. To estimate the pH of the sample, Tricia used a pH strip. Tricia collected 0.001 L of the sample, which came out to have a pH of around 3.3. Furthermore, Tricia made a new setup in which 0.001 L of the same sample was diluted with 0.009 L of water, and the pH taken was now around 3.8. The second method is Titration, and Jillian used this method. Jillian prepared a 0.010 L aliquot of the sample and diluted it with 0.025 L of distilled water. After this, Jillian added 2 drops of phenolphthalein, and it was titrated 0.00354 L of 48 mmol standardized NaOH to the endpoint. With this, answer the following questions. Questions: 1. Using the data in the titration method, compute the molarity of the acid. 2. Predict the pH of the sample, assuming that the titrated unknown is a strong acid. 3. Calculate the [H+] concentration in the sample before dilution using the values from the pH
