Question

How many atoms are there in a single molecule of ammonia?

Answer 1

Hint : In the given question, we are required to find the number of atoms in a single molecule of ammonia. We must remember the formulae for chemical compounds so as to solve such questions in which we have to count the number of atoms. Ammonia is a compound of nitrogen and hydrogen.

Complete Step By Step Answer:
So, we need to calculate the number of atoms in the chemical substance given the question. The chemical compound given to us in the problem is ammonia.
Ammonia is a stable binary hydride. It is a colorless gas with a distinct characteristic of a pungent smell. It is also a common nitrogenous waste among aquatic animals. It is also a major ingredient in fertilizers and pesticides.
So, the formula for the compound ammonia is $N{H_3}$ .
Hence, a single molecule of ammonia consists of three atoms of hydrogen and one atom of nitrogen. Therefore, the total number of atoms in a single molecule of ammonia is four.

Note :
Ammonia is a chemical substance that is used in many industrial processes. One must know the formula for ammonia so as to solve such questions. We also must know the difference between the empirical formula and the actual formula of a chemical compound.
