Number of N atoms in 0.650mol NH3. The Correct Answer and Explanation is: Correct Answer: To find the number of nitrogen atoms in 0.650 mol of ammonia (NH₃), we follow this step: Each NH₃ molecule contains 1 nitrogen atom. So, in 0.650 mol of NH₃, there are: 0.650 mol NH₃×6.022×1023 molecules1 mol×1 N atom1 NH₃ molecule=3.91×1023 N atoms0.650 \text{ mol NH₃} \times \frac{6.022 \times 10^{23}
