A GC separation was conducted on a sample containing a 14) pesticide analyte, Pymetozine. This sample was treated with an internal standard of chlorobenzene, giving a concentration of 15.0 ppm. A 1.0 uL injection onto the GC gave an FID response of 1012 for chlorobenzene and 3411 for Pymetozine. A 1.0 uL standard solution of 30.0 ppm chlorobenzene with 15.0 ppm of Pymetozine was injected giving response of 899 and 2791 respectively. What is the concentration of Pymetozine in the sample?
