Answer:
To find the percentage of nitrogen in nitrogen monoxide (NO), we need to calculate the molar masses of nitrogen (N) and oxygen (O), and then determine what fraction of the molar mass of NO is due to nitrogen.
### Step-by-Step Calculation:
1. **Molar Mass of Nitrogen (N):**
- Atomic mass of N = 14.01 g/mol
2. **Molar Mass of Oxygen (O):**
- Atomic mass of O = 16.00 g/mol
3. **Molar Mass of NO:**
- Molar mass of NO = Molar mass of N + Molar mass of O
- Molar mass of NO = 14.01 g/mol + 16.00 g/mol = 30.01 g/mol
4. **Percentage of Nitrogen in NO:**
- Percentage of N in NO = (Molar mass of N / Molar mass of NO) × 100%
- Percentage of N in NO = (14.01 g/mol / 30.01 g/mol) × 100%
- Percentage of N in NO = 0.4665 × 100%
- Percentage of N in NO ≈ 46.65%
So, the percentage of nitrogen in nitrogen monoxide (NO) is approximately 46.65%.
