1. The molar coefficient of light absorption of the complex of indium with catechol violet is 35900 at a wavelength of 630 nm. Determine the content of indium in the solution in g/l, if the relative optical density of the test solution, measured in a cuvette with a light-absorbing layer thickness of 1 cm in relation to the reference solution containing 0.0006 mol/l of indium, turned out to be 0.45.
