6. The molar light absorption coefficient of Cu(II) dithizonate in CCl4 at λ=550nm is 4.52*104. What is the MINIMUM CONTENT of Cu in (%) copper can be determined with dithizone, if 25.00 ml of a solution of dithizonate in CCl4 is obtained from a sample of an alloy weighing 1.00 g and the minimum optical density is measured in a cuvette l = 5.0 cm.
