Correct Answer: 7
Solution and Explanation
The chemical formula for fuming sulfuric acid is $\text{HSO}_3\text{SO}_3$, also known as oleum.
The number of oxygen atoms in the formula is calculated by counting the oxygens in both parts of the formula:
- $\text{HSO}_3$ contributes 3 oxygen atoms. - $\text{SO}_3$ contributes 3 oxygen atoms.
Thus, the total number of oxygen atoms in fuming sulfuric acid is $3 + 3 + 1 = 7$. Therefore, the correct answer is 7.
