田囚 Add-ons Help Last edit was 3 minutes ago BIUA Trebuchet... 10.5 X|四凹 ,山, … g一 三 三三三. 3. The active ingredient in aspirin is acetylsalicylic acid (ASA;formula C, H, O,) A commercial aspirin tablet was ground to fine powder. Exactly 0.361 g of this powdered tablet was transferred to an Erlenmeyer flask and dissolved in a 50 mL alcohol-water solution. A drop of phenolphthalein indicator was added to the solution. This solution was titrated against the standardized NaOH. Initial burette reading is 28.35 mL. The burette read 42.60 mL when a permanent pale pink color was obtained. (i) Find the molarity of acetyl salicylic acid(asa) in the flask 0.02003 (ii) Find the mass of acetylsalicylic acid in the flask. 0.361 g (iii) Find the percent mass of acetylsalicylic acid in the tablet. 98.9% Table 5: Aspirin Titration Data Initial Burette Reading (NaOH) 28.35 mL Final Burette Reading (NAOH) 42.60 mL Volume of NaOH Required for 14.25 mL Endpoint Molarity of NaOH 0.2832 M Concentration of ASA (Molarity) Volume of Aspirin Solution used 50.00 mL Find the moles and grams of ASA in your Aspirin sample using your knowledge of Stoichiometry And Calculate % Mass of ASA in your sample as shown below: % Mass of ASA = X 100 +) V
