100. Solving a chemistry problem

1. Calculate the iron content in 50 ml of the analyzed solution according to the results of photometry using the addition method. The optical density of the test solution prepared from 5 ml of the analyzed solution is 0.45; the value of the optical density of the same test solution with the addition of 100 μg of iron, measured under the same conditions, is 0.85.
