The number of nitrogen atoms in ammonium acetate is

ammonium acetate, and its chemical formula is\ (CH_ {3} COONH_ {4}\). From its chemical formula, each ammonium acetate molecule contains\ (1\) nitrogen atoms.

If the amount of ammonium acetate is known to be\ (n\) \ (mol\), according to\ (N = nN_ {A}\) (\ (N\) is the number of particles,\ (n\) is the amount of substance,\ (N_ {A}\) is the Avogadro constant, which is about\ (6.02 × 10 ^ {23} mol ^ {-1}\)), then the amount of nitrogen atom is equal to the amount of ammonium acetate substance, also\ (n\) \ (mol\), the number of nitrogen atoms\ (N_ {N} = nN_ {A}\).

For example, if there is\ (1mol\) ammonium acetate, the number of nitrogen atoms in it is\ (6.02 × 10 ^ {23}\); if the amount of ammonium acetate is\ (0.5mol\), the number of nitrogen atoms is\ (0.5 × 6.02 × 10 ^ {23} = 3.01 × 10 ^ {23}\).

Therefore, to determine the specific number of nitrogen atoms in ammonium acetate, the amount of ammonium acetate must be determined first, and then calculated according to the above relationship.
