To determine the number of oxygen atoms in one molecule of trinitrotoluene (C₆H₃(NO₂)₃), we can analyze its chemical formula.
The formula C₆H₃(NO₂)₃ indicates that there are three nitro (NO₂) groups attached to the toluene structure. Each nitro group contains 2 oxygen atoms.
So, we calculate the total number of oxygen atoms:
- Each NO₂ has 2 oxygen atoms.
- There are 3 NO₂ groups in the formula.
Total oxygen atoms = 3 (NO₂ groups) × 2 (oxygen atoms per NO₂) = 6 oxygen atoms.
Therefore, the correct answer is:
**6**
