Product description
36. To determine the content of methyltestosterone in the tablets of its preparation (the declared content of methyltestosterone in one tablet is 0.0045-0.0055 g), a sample weighing m = 0.0500 g of the drug was transferred to an alcohol solution with a volume of V (X) = 250 ml, the optical density was measured A(X) of the resulting solution at a wavelength λ=240 nm, thickness of the absorbing layer l=1 cm and found A(X)=0.535.
Calculate the content of methyltestosterone in milligrams per one tablet, if the mass of the tablet is m=0.1000 g, and the specific redemption ratio of the alcohol solution of methyltestosterone is E=535. Does the calculated content of methyltestosterone correspond to the declared one?
