35. Solving a chemistry problem

238. Using the internal standard method, calculate the content (%) of hexane (1) and heptane (2) in the analyzed mixture. Octane (st) was chosen as the internal standard. A standard mixture containing the same amount of these three components, 0.06 g each. Chromatographed (GZ, GLC). The areas of these peaks turned out to be 36.47 and 45 mm2, respectively. The analyzed mixture weighing 0.09 g, containing 0.045 g of octane, was chromatographed. The peak areas corresponding to the sequence of their listing given above were 46 mm2, 21 mm2 and 41.2 mm2.
