111. Solving a chemistry problem

89. Calculate the determined minimum for the photoelectrocolorimetric analysis of iron (in μg) with sulfosalicylic acid in ammonia medium. The thickness of the absorbing layer is 1 cm, the minimum volume of the colored solution in the flask is 25.00 . The average value of the molar coefficient of light absorption of the complex is 4000. The minimum optical density measured by the device = 0.01.
