A scientist wishes to measure the concentration of methyl benzoate in a plant stream by gas chromatography. He prepares a sample of butyl benzoate to use as an internal standard. The results of a preliminary run, which used a solution known to contain 1.67mg/mL of methyl benzoate (peak A) and 1.84mg/mL of butyl benzoate (peak B), are shown. The area of peak A is determined to be 368 and the area of peak B is determined to be 417 measured in arbitrary units by the computer. To measure the sample, 1.00mL of a standard sample of butyl benzoate containing 2.47mg/mL is mixed with 1.00mL of the plant stream material. Analysis of the mixture gave a peak area of 455 for peak A and 427 for peak B. What is the concentration of methyl benzoate in the plant stream
