Answer

To find the total number of atoms in one molecule of the product formed from glycerol when treated with potassium hydrogen sulfate and heated, we can follow these steps:

### Step 1: Identify the structure of glycerol
Glycerol has the molecular formula C₃H₈O₃. Its structure can be represented as:
```
CH2OH
|
CHOH
|
CH2OH
```

### Step 2: Understand the reaction with potassium hydrogen sulfate
When glycerol is treated with potassium hydrogen sulfate (KHSO₄) and heated, it undergoes dehydration. This means that it loses water molecules (H₂O).

### Step 3: Determine how many water molecules are lost
In this reaction, glycerol loses 2 molecules of water (H₂O) to form a product called acrylic aldehyde (C₃H₄O).

### Step 4: Write the molecular formula of the product
After losing 2 water molecules, the molecular formula of the product (acrylic aldehyde) can be derived:
- Starting with C₃H₈O₃ (glycerol)
- Losing 2 H₂O (which is 2 H and 1 O for each H₂O, so 4 H and 2 O total)
- The resulting molecular formula is C₃H₄O.

### Step 5: Count the total number of atoms in the product
Now, we can count the total number of atoms in acrylic aldehyde (C₃H₄O):
- Carbon (C): 3 atoms
- Hydrogen (H): 4 atoms
- Oxygen (O): 1 atom

Adding these together gives:
3 (C) + 4 (H) + 1 (O) = 8 atoms in total.

### Conclusion
The total number of atoms in one molecule of the product formed is **8**.
