Here is the information that I figured out before the question, and
I underlined the question at the bottom of the page.
Dilution--Absorbance (a.u.)
2:11--0.123 & 4:11--0.215 & 6:11--0.336 & 8:11--0.454 & 10:11--0.577
Mass of tablet : 0.360 g  
Absorbance read on the Spec 20 : 0.318 a.u.
Calculate the number of moles of ASA:0.00277
Calculate the molar concentration of the 250 mL solution of ASA:0.0111
Calculate the molar concentration of the 100 mL solution of ASA:0.00111
Dilution--Molarity (dilutions)
2:11--0.000201 & 4:11--0.000403 & 6:11--0.000604 & 8:11--0.000806   & 10:11--0.00101
With the absorbance of the prepared tablet solution and using the Standard Beer's Law plot (based on the ASA dilutions) determine the concentration of this solution
0.000562  M
Using reverse dilution, calculate the initial concentration of the tablet solution:
Calculate the number of moles in the 100 mL diluted solution.
Calculate the mass (g) in the 100mL diluted solution.
