C44H34O22 is a chemical formula that shows the molecule contains 44 carbons, 34 hydrogens, and 22 oxygens. But the same formula can correspond to several different molecules, known as isomers. So, this formula alone doesn’t identify a single compound. To know the exact substance, you need more information such as the structure, the IUPAC name, or experimental data (for example, NMR or mass spectrometry). In short, the formula indicates composition, not the exact arrangement of atoms.
