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