ww.rack Cailations: The active ingredient of aspirin is acetylsalicylic acid. Acetylsalicylic acid can be represented by either diagram below: H C-H What is the chemical formula of acetylsalicylic acid? The only ionizable hydrogen (hydrogen that can dissociate from the rest of the molecule) is the one attached to an O. Find it! Circle it in both representations. Using your data and using the calculated molarity of the base from experiment 1 (or 0.10 M if using video), calculate the mass of acetylsalicylic acid that must have been originally present in your crushed aspirin. (Here is the reaction: HC9H7O4 + NaOH O NaCoHO4 + HОН) Tip: DO NOT SOLVÉ THE WAY THE TEACHER IN THE VIDEO DID. WE ARE NOT USING THAT EQUATION, NOR ARE WE SOLVING FOR MOLARITY. Use dimensional analysis. 1. Given: .10 Molarity .325g Aspirin HСЭН704 + NaОН %3D NaC9H704 + НОН Unknown: Mass of acetylalicylic acid in aspirin 1. Determine the percent of acetylsalicylic acid in aspirin.
