You wish to measure the concentration of methyl benzoate in a plant stream by gas chromatography. You prepare a sample of butyl benzoate to use as an internal standard. A preliminary run, shown at the right involved a solution containing 1.69 mg/mL of methyl benzoate (peak A) and 1.86 mg/mL of butyl benzoate (peak B). The area of peak A was determined to be 354 and of peak B to be 419 (measured in arbitrary units by the computer). To measure the sample, 1.00 mL of a standard sample of butyl benzoate containing 2.59 mg/mL was mixed with 1.00 mL of the plant stream material, and analysis of the mixture gave a peak area of 463 for peak A and 425 for peak B. What is the concentration of the ethyl benzoate in the plant stream?
