Number of molecules of oxygen produced along with one molecule of sugar

6 molecules of Oxygen

Explanation:

From the question,

Sugar has a molecular formula of C₆H₁₂O₆.

Hence,

Using the mole concept, i. e.,

1 molecule of Sugar, i. e., C₆H₁₂O₆ has, 6 molecules of Carbon, 12 molecules of Hydrogen and 6 molecules of Oxygen.

Therefore,

6 molecules of Oxygen is present in 1 molecule of sugar, i. e., C₆H₁₂O₆.
