How many atoms are in the following molecules of ammonia: 3 (NH3)

3

4

8

12

The answer to your question is 12 atoms

Explanation:

Data

Number of atoms = ?

Molecule = ammonia

Process

1. - Calculate the number of atoms on ammonia

NH₃ = 1 atom of Nitrogen and 3 atoms of hydrogen

2. - Calculate the total number of atoms considering the coefficient 3

3 (NH₃) = (1 x 3) atoms of Nitrogen + (3 x 3) atoms of hydrogen

3 (NH₃) = 3 + 9

3 (NH₃) = 12 atoms
