**Topic:** Compounds and Molecular Formulas
**Question:**
An oxide of nitrogen contains 30.45 mass % N and has a molar mass of 92.02 g/mol. What is the molecular formula?
**Options:**
- NO₅
- N₃O₂
- N₄O₂
- NO₂
- N₂O₄ (Correct answer)
**Explanation:**
To determine the molecular formula, consider the given data:
1. **Percentage Composition:** 30.45% of the compound’s mass is nitrogen (N).
2. **Molar Mass:** The compound has a molar mass of 92.02 g/mol.
The correct formula, N₂O₄, satisfies these conditions when accounting for the atomic weights of nitrogen and oxygen:
- Nitrogen (N) has an atomic weight of approximately 14.01 g/mol.
- Oxygen (O) has an atomic weight of approximately 16.00 g/mol.
By applying these weights to the given options, N₂O₄ matches the specified conditions, confirming it as the correct answer.
