To construct a calibration graph of hydroquinone, its standard solutions with concentrations of 0.10, 0.20, 0.50, 1.00, and 2.00 mg / L were taken. Chromatographic analysis of these samples showed that the areas of the peaks of the standard solutions will be 15.31, 74.146 and 287 mm2, respectively. Then a sample of unknown concentration was taken, the peak area of which was 43 mm2. Establish the mass concentration of hydroquinone in an unknown sample.
