Here's how to determine the number of oxygen atoms in the molecule 4C12H22O11:

* The subscript "11" after the oxygen (O) indicates there are 11 oxygen atoms in one molecule of C12H22O11.

* The coefficient "4" in front of the molecule means there are 4 molecules of C12H22O11.

Therefore, there are a total of 11 oxygen atoms per molecule * 4 molecules = 44 oxygen atoms.
