To measure the concentration of benzene in a gasoline samplethe internal standard toluene is added to the sample. When benzeneand toluene are at the sme concentration te gas chromatogramproduces a peak height for benzene that is 3.74 times greater thanthat of toluene. For this analysis 7 ml of gasoline is mixed with1.55 ml of solution containing 89 mg of toluene. When analyzed bygas chromatography the peak areas for benzene and toluene are 6382and 4793 respectively. Determine how many milligrams of benzene are in the initial 7 ml of gasoline.
