Final answer:
In ammonia (NH3), the total number of protons is 14.
Step-by-step explanation:
The molecular formula for ammonia is NH3. To calculate the total number of protons (p) in ammonia, we can find the atomic number of nitrogen (N), which is 7, since ammonia contains one nitrogen atom. The atomic number of an element represents the number of protons in its nucleus. So, there are 7 protons in one molecule of ammonia. Therefore, the correct answer is A. 14.
