Question

how many nitrogen atoms are present in one molecule of dinitrogen pentoxide? n₂o₅ 7 atoms 5 atoms 2 atoms 6.02 x 10²³ atoms

Explanation:

Step1: Analyze the chemical formula

The chemical formula of dinitrogen pentoxide is $N_2O_5$. In a chemical formula, the subscript to the right of an element symbol indicates the number of atoms of that element in one molecule of the compound.

Step2: Determine the number of nitrogen atoms

For nitrogen (N) in $N_2O_5$, the subscript is 2. This means there are 2 nitrogen atoms in one molecule of dinitrogen pentoxide.

Answer:

2 atoms (the option with "2 atoms")
