(a)
Interpretation : The empirical formula for the given compound should be calculated.
Concept Introduction : For any compound the empirical formula represents the lowest whole number ratio of atoms in a compound. It does not represent the actual number of atoms in the molecule. The relation between molecular formula and empirical formula can be written as;
Molecular formula = small integer x empirical formula

- (2 pts) Estradiol is a potent female hormone. In 1934, Edward A. Doisy of Washington University extracted 3000 lb of hog ovaries to isolate a few milligrams of pure estradiol. Doisy burned 5.00 mg of this precious sample in oxygen and found that 14.54 mg of CO2 and 3.97 mg of H20 were generated. 3. (a) Determine the empirical formula of estradiol.
