Answer:
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
