In 1934, Edward A. Doisy of Washington University extracted 3000 lb of hog ovaries to isolate a few milligrams of pure estradiol, a potent female hormone. Doisy burned 5.00 mg of this precious sample in oxygen and found that 14.54 mg of CO2 and 3.97 mg of H2O were generated.

1.) Determine the empirical formula of estradiol.

2.) The molecular weight of estradiol was later determined to be 272. Determine the molecular formula of estradiol.

(express answer as a condensed structural formula)
