I already answered a, but I need help with b and c. I'm super confused, especially on how I'm supposed to calculate the extinction coefficient.

2. Use the data table for cureumin to answer the following questions. Table 1: Beer's Law data for curcumin standards at mm 1 L Concentration (M) 4.00E- 05 2.00E-OS 1 .50E-OS 100F-OS 5.00E-06 Absorbance (max) .77 1.13 0.87 0.59 0.38 1 a. Plot the data points given in the table on the following graph. Use a ruler to draw a best-fit line. Calibration Curve for Curcumin 2.00 1.80 Absorbance at 0.40 0.20 0.00 0.00E+00 4.00E-05 5.00E-05 1.005-05 152.00E-05 3.00E-05 Concentration (M) b. Calculate the extinction coeflicient for curcumin from the slope of your graph and explain its significance. Assume a path length of Icm. c. Your lab partner brings you another sample at a concentration of 5.00x10 M. You record the absorbance and the instrument reads 2.15. Do you think you should include this data in your plot and resolve for the slope? Why or why not? 2. Use the data table for cureumin to answer the following questions.
