61. Solving a chemistry problem

1. In a sample of meat pate weighing 10 g after appropriate processing, the tin content was determined by the photocolorimetric method. Calculate the concentration of tin in the sample in µg/g and in percent if the optical density of the solution at a cuvette layer thickness of 2 cm is 0.038. The molar absorption coefficient of the solution is 31000. The volume of the resulting solution is 1000 cm3.
