Question
If, during the experiment, the following data were obtained, determine the content of acetylsalicylic acid in the tablets. The molar mass of aspirin is 180.158 mg/mmol. Total mass of the two aspirin tablets (g) = 0.2500 Molarity of NaOH (mmol/mL) = 0.1204 Volume of NaOH used (ml) = 50.00 Molarity of HCI (mmol/mL) = 0.09088 Volume of HCl used to titrate (ml) = 9.35 Manufacturer's indicated acetylsalicylic acid content per tablet (mg) 80.0 Find the following: mmol of NaOH initially added: mmol of NaOH back-titrated: mmol of NaOH that reacted: mg of acetylsalicylic acid in the analyzed sample: mass percent of acetylsalicylic acid in the sample: mg of acetylsalicylic acid per tablet: percent error (based on indicated content):_
