2. One table of brand Y aspirin was dissolved in 10 mL of 1.0 M NaOH, boiled,and then dilute to a final volume of 100 mL with deionized water. A 2.5 mL aliquot of this concentration aspirin solution was 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 of 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 diluted aspirin solution? b) What is the concentration of the original aspirin solution? c) How many mg of aspirin are present in one table of Brand Y aspiring?
