Question
**Text for Educational Website:** --- ### Molar Mass and Reaction Calculations **8. Molar Masses of Salicylic Acid and Acetic Anhydride** - **Objective:** Find the molar masses of salicylic acid and acetic anhydride, and record the density of acetic anhydride. - The molar mass of salicylic acid is **138.121 g/mol**. - The molar mass of acetic anhydride is **102.09 g/mol**. **9. Calculating Moles of Reactants** - **Task:** Calculate the moles of salicylic acid and acetic anhydride used in your reaction. You can write your work on paper, capture a photo of it using your phone, and paste the image into your Electronic lab notebook. - Moles of Salicylic Acid: **0.00342 mol** - Moles of Acetic Anhydride: **0.00004464 mol** **10. Reaction Production** - **Statement:** For every one mole of salicylic acid that reacts, one mole of aspirin is produced. - **Calculation:** Use your answer from question 9 to calculate the number of moles of aspirin that would be produced if all of the salicylic acid reacted. - Due to the ratio being equal, it would be **0.00342 mol of aspirin**. **11. Acetic Anhydride Reaction** - **Statement:** For every one mole of acetic anhydride that reacts, one mole of aspirin is produced. - **Calculation:** Use your answer from question 9 to calculate the number of moles of aspirin that would be produced if all of the salicylic acid reacted. ---
