Here's a breakdown:

* C₂₂H₂₄N₂O₈: This represents the doxycycline molecule itself, with 22 carbon atoms, 24 hydrogen atoms, 2 nitrogen atoms, and 8 oxygen atoms.

* HCl: This represents the hydrochloric acid (hyclate) molecule, which is bound to the doxycycline molecule.

Therefore, the complete molecular formula for doxycycline hyclate includes both the doxycycline and the hydrochloric acid molecules.
