The number of oxygen atom in paracetamol is …..

Explanation

To determine the number of oxygen atoms in paracetamol, we can follow these steps:

### Step 1: Identify the Chemical Formula of Paracetamol
Paracetamol, also known as acetaminophen, has the chemical formula C8H9NO2.

### Step 2: Break Down the Chemical Formula
In the formula C8H9NO2:
- C represents carbon atoms (8 in total)
- H represents hydrogen atoms (9 in total)
- N represents nitrogen atoms (1 in total)
- O represents oxygen atoms (2 in total)

### Step 3: Count the Number of Oxygen Atoms
From the chemical formula, we can see that there are 2 oxygen atoms present in paracetamol.

### Conclusion
Therefore, the number of oxygen atoms in paracetamol is **2**.
