Selective analysis of an analyte and internal standard yielded detector responses of 3.47 and 5.23 respectively when each had a concentration of 1.00 ppm. Five mL of an unknown analyte solution were mixed with 1 mL of 5.00 ppm internal standard and then diluted to a total of 10 mL. The detector responses for analyte and internal standard for this mixture were 4.26 and 2.43. Calculate the concentration of the analyte in the unknown solution. Report your answer in ppm.
