QUESTION:
Cortisol \((ℳ =362.47 \mathrm{~g} / \mathrm{mol})\), one of the major steroid hormones, is used in the treatment of rheumatoid arthritis. Cortisol is \(69.6 \% \mathrm{C}, 8.34 \% \mathrm{H}\), and \(22.1 \% \mathrm{O}\) by mass. What is its molecular formula?
ANSWER:
Step 1 of 2
Here, we find the molecular formula of Cortisol.
First. Let's calculate the empirical mass of Cortisol.
Empirical formula of Cortisol \(=\mathrm{C}_{4.2} \mathrm{H}_{6} \mathrm{O}\)
Molar mass of \(\mathrm{C}=12.0 \mathrm{~g}\)
Molar mass of \(\mathrm{H}=1.008 \mathrm{~g}\)
Molar Mass of \(O=16 \mathrm{~g}\)
