In Experiment 1, a student determined the aspirin content of a tablet by a back titration procedure. The weight of the student’s tablet was 1.5500 g. After crushing and dissolving the tablet, the student added 54.00 mL of 0.1000 M NaOH. The back titration of the excess NaOH required 18.00 mL of 0.2000 M HCl. How many moles of aspirin were in the tablet?

A 0.1019 - g portion of an aspirin tablet was dissolved in sufficient water to prepare 1.000 liter of solution. A pipet was used to transfer 10 mL of the solution to a 100 - mL volumetric flask. A 2 - mL portion of 4 M sodium hydroxide solution was added to the flask, and the resulting solution was diluted to the mark with water. The fluorescence of the diluted sample solution was found, by the working curve method, to...

II. Digestion of Acetylsalicylic acid(standard and tablet) with NaOH . Digestion of Acetylsalicylic Acid Standard to Prepare Stock Solution: Obtain ca. 0.1 g dried acetylsalicylic acid (MM = 180.16 g/mol), accurately weighed, and quantitatively transfer to a 125-ml Erlenmeyer flask. Add 5 ml 1.0 M NaOH and heat mixture to boiling on a hot plate. This will hydrolyze the acetylsalicylic acid to sodium salicylate. If necessary, rinse down the walls of the Erlenmeyer with DI water to ensure complete hydrolysis...

1. A volume of ___ mL of 0.100 M NaOH(aq) is required to titrate 0.500 g of potassium hydrogen phthalate (often abbreviated KHP) to the endpoint. 2. A 0.5741 g sample of a monoprotic acid was titrated with 0.1008 M NaOH(aq). If 37.89 mL of sodium hydroxide solution were required for the titration, the molar mass of the monoprotic acid is ___ g/mol.
