show me how to work this problem and the answer
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 1.91 mg/mL of methyl benzoate (peak A) and 2.10 mg/mL of butyl benzoate (peak B). The area of peak A was determined to be 306 and of peak B to be 354 (measured in arbitrary units by the computer). To measure the sample, 1.00 mL of a standard sample of butyl benzoate containing 2.33 mg/mL was mixed with 1.00 mL of the plant stream material, and analysis of the mixture gave a peak area of 453 for peak A and 399 for peak B for pealk A ana 109 f r peak g of the mture gave a peak area of 459 What is the concentration of the methyl benzoate in the plant stream? 10 Time (min) 15 Number conc.methyl benzoate mg/mL
