A sample contains 200 atoms of hydrogen, 0.05 gm atom of nitrogen, 1020 gm atom of oxygen. What is the approximate no. of total atoms

Question

**Options:**
- **A.** [object Object]
- **B.** [object Object]
- **C.** [object Object]
- **D.** [object Object]

---
**Difficulty:** EASY | **Chapter:** Mole concept | **Topic:** Law of chemical combination, atomic & molecular mass, mole concept, calculations

Accepted Answer

## ✅ Correct Answer: **C**

### 📖 Detailed Explanation:
This question uses atomic structure & atomic mass, mole concept & particle counting. Convert all given quantities into moles using n = given amount/molar mass, use Avogadro's number where needed to get particles, and then compare with the options; this matches option C.
