72. In determining the palladium in the electrolyte used the method of calibration curve. Before analysis, the electrolyte was diluted 100 times. The atomic absorption of this solution at 244.79 nm is 0.440. To construct the calibration graph, a series of standard solutions was prepared with a concentration of 5.0, 10.0, 15.0, 20.0, and 25.0 μg of Pd in 1.0 ml. The atomic absorption of these solutions is 0.165 0.340 0.500 0.680 and 0.920, respectively. To determine the concentration of palladium in the electrolyte (g / l)?
