1. Make a scatter plot (on the computer again) of absorbance versus concentration for the calibration samples. On the plot, add a linear trendline and display the equation on the chart. Take your time to label the axes. Attach the chart to the end of this experiment.
2. From your plot, what is the value of εb?
Absorption Concentration
0.822 0.00056
0.776 0.000448
0.516 0.000336
0.455 0.000224
0.335 0.000112
3. For the aspirin sample, calculate the concentration of acetylsalicylic acid present using the value of εb that you found.
4. The concentration from analysis question 5 represents the concentration in the 10.00 mL sample that was prepared in the volumetric flask using an aliquot of the solution in the 100.00 mL volumetric flask. Calculate the concentration of acetylsalicylic acid in the 100.00 mL volumetric flask. This is a simple dilution – as long as you use the correct volumes!
5. Using your result from the previous question, determine the mass of acetylsalicylic acid in the tablet.
