112. The reaction mass after nitration of toluene was analyzed by gas-liquid chromatography using ethylbenzene as an internal standard.
Determine the mass fraction (ω, %) of unreacted toluene according to the following experimental data: taken mtoluene, g = 12.75, methylbenzene, g = 1.25; peak areas =307 (k=1.01), =352 (k=1.02) were obtained.
