Step-by-step explanation:
The chemical formula NH3 represents ammonia, a colorless gas that is widely used in various industrial and household applications. The formula indicates that one molecule of ammonia contains one nitrogen atom and three hydrogen atoms. Therefore, the ratio of nitrogen to hydrogen in ammonia is 1:3.
This means that for every one nitrogen atom in an ammonia molecule, there are three hydrogen atoms. Alternatively, we can say that the ratio of nitrogen atoms to hydrogen atoms in ammonia is 1:3.
