Here's how to figure out the number of oxygen atoms in a sucrose molecule:

* Sucrose's Chemical Formula: The chemical formula for sucrose is C₁₂H₂₂O₁₁.

* Subscripts Indicate Number of Atoms: The subscripts in the formula tell you how many atoms of each element are present in one molecule.

* Oxygen Atoms: The subscript for oxygen (O) is 11.

Therefore, there are 11 oxygen atoms in one molecule of sucrose.
