Answer

To determine the total number of nitrogen (N) atoms present in veronal, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Compound**: Veronal is also known as barbitone. It is important to know the chemical structure of veronal to count the nitrogen atoms.

2. **Draw the Structure**: The structure of veronal can be represented as follows:
- It consists of a pyrimidine ring with two ethyl groups attached to it.
- The chemical formula for veronal is C_7H_12N_2O_3.

3. **Count the Nitrogen Atoms**: In the structure of veronal, we need to identify how many nitrogen atoms are present.
- Upon examining the structure, we can see that there are two nitrogen atoms in the molecule.

4. **Conclusion**: Therefore, the total number of nitrogen atoms present in veronal is **2**.

### Final Answer:
The total number of N-atoms present in veronal is **2**.
