A 0.2422 g sample of a certain fruit was analyzed for the content of a certain pesticide. After a series of extraction steps, the final extract obtained was diluted to 10.00 mL, which was then subjected to chromatographic analysis. Four standard solutions of the pesticide were also prepared, processed, and analyzed in the same manner. The data obtained are shown in the table below. Concentration (µg/mL) Peak Area Solution Standard 1 0.01 234.2 Standard 2 0.05 1101.2 Standard 3 0.10 2300.1 Standard 4 0.20 4999.8 Sample ? 1654.3
