45. Solving a chemistry problem

36. The molar absorption coefficient of the complex of beryllium with acetylacetone in chloroform for a wave of 295 nm is 31600. What is the minimum content of beryllium (in%) can be determined in a sample of 1 g, dissolved in 50 ml, in a cuvette with a layer thickness of 5 cm, taking the minimum report on optical density scale of the photocolorimeter 0.025? In the colored compound, there is 1 molecule of acetylacetone per beryllium atom.
