37. Solving a chemistry problem

160. The molar absorption coefficient of the complex of beryllium with acetylacetone in CHCl3 at a wavelength of 290 nm is 30000. What is the minimum content of beryllium (in%) can be determined in a sample of 1.0000 g, dissolved in 50.0 ml in a cuvette with l = 5 cm, if the minimum value of optical density, which can be measured with satisfactory accuracy on FEK-M, is 0.02? In the colored compound, the ratio of beryllium and acetylacetone is 1:1.
