20. What is the purpose of the concentrated sulfuric acid used in the experiment? What would happen if this chemical were left out? Suggest a chemical that can be used to replace the concentrated sulfuric acid
Moles of salicylic acid 3g/138.12g=0.022 moles of salicylic acid (limiting reagent) Moles of acetic acid 6mL/1.08 g/mL x Imole / 60.05 g -0.093 moles 0.022 moles of aspirin x 180.16g/mol = 3.96g of aspirin 10. Calculation of percent of experiment yield (show calculation) Percentage yield obtained = Experiment yield -X100% theoretical yield 2 moles of aspirin will be produced from 2 moles of salicylic acid (1 to 1) Theoretical aspirin yield = 3g 3g of salicylic acid (limiting reagent) x (180g of aspirin/138g of salicylic acid) = 3.91(theoretical yield) -2.908 g/ 3.91 g x 100 - 74.37% OR = 2.908 g 3.96 g x 100 - 73.43%
9. Calculation of theoretical yield (show calculation) Theoretical yield of aspirin Moles of Salicylic Acid-Moles of Aspirin-> 2 moles of Salicylic Acid makes 2 moles of Aspirin (1 to 1) Synthesis of Aspirin Page 5 Molar Mass of Aspirin - 180.16 g Volume-> mass -> 1.08 g/mL Theoretical yield of Aspirin (g) - (3 moles)(molar mass of aspirin) - 3.000(180.16) - 540.48 grams.
