Reference no: EM131599388

One tablet of Brand Y aspirin was dissolved in 10mL of 1.0 M NaOH, boiled, and then diluted to a final volume of 100 mL with FeCl3. A calibration plot of absorbance vs. concentration was obtained, with the slope of the best-fit straight line as 1370 M^-1. The diluted aspirin solution had an absorbance of 0.932. What is the concentration of the dilute aspirin?

a. What is the concentration of the aspirin in the dilute aspirin solution?

b. What is the concentration of the original aspirin solution?

c. How many mg of aspirin are present in one tablet of Brand Y aspirin?
