Verified step by step guidance1
Identify the molecular formula of glucose, which is given as C6H12O6. This formula tells us the number of atoms of each element in one molecule of glucose.
Focus on the oxygen atoms in the formula. The subscript number following the oxygen symbol (O) indicates how many oxygen atoms are present in one molecule.
In the formula C6H12O6, the subscript for oxygen is 6, meaning there are 6 oxygen atoms in one molecule of glucose.
No further calculations are needed because the molecular formula directly provides the count of oxygen atoms.
Therefore, the number of oxygen atoms in one molecule of glucose is equal to the subscript number 6 in the formula C6H12O6.
