Question

i am stuck on the last two parts of the table. cpuld you check my work and complete the questions?

Part IlI Beer's Law Data for Salicylic Acid Standard Solutions Concentration Trial 2.180 | 2.90x10.ฯ าเว 0.9866 Best-fit line equation for the salicylic acid standards 33640. Test of the Purity of the Synthesized Aspirin Initial mass of aspinin sample (g) Absorbance of aspirin sample Moles of salicylic acid in aspirin sample (mol) Mass of salicylic acid in aspirin sample (g) Mass of aspirin in sample (g) Percent aspirin in sample (%) 40 , 706 , ool4 DATA ANALYSIS 1. What is the theoretical yield of aspirin in your synthesis? The mole ratio is 1:1 between salicylic acid and acetic anhydride in this reaction. The melting temperature of pure acetylsalicylic acid is 135°C. Based on the results of the O53 melting temperature test, what is the percent purity of your sample of aspirin? 2. Based on the results of the absorbance testing, what is the percent purity of your sample of aspirin? Does this percent purity compare well with the results of the melting temperature 3. test? Explain. Use your percent purity calculations to determine the percent yield of your synthesis of aspirin. 4. Use your text, or another suitable resource, to find the structural formulas for salicylic acid, acetic anhydride, and aspirin. Use these structura describing the synthesis of aspirin. 5.
