13. Flutamide (Eulexin) is an important organic compound containing
three fluorine atoms in each molecule. It is used in the treatment of
prostate cancer. An analytical chemist extracted flutamide from a
commercial tablet weighing 203.21 mg leaving a residue (containing
non-medicinal ingredients) that weighed 128.23 mg. Elemental analysis
of the extracted flutamide revealed the presence of 15.47 mg of
fluorine. What is the molar mass (in g mol–1) of flutamide?
I feel quite stumped on this question. It is a question from a past competition, and the answer is C.
The progress I have made so far is that the mass of the flutamide is 75.98mg, with 15.47mg of it being fluorine. Otherwise, I can't seem to make the logical next step. Anyone feel like pushing me in the right direction?
