Answer : The number of atoms of oxygen present in [tex]2Fe(NO_3)_2[/tex] are, 12.
Explanation :
As we know that, [tex]Fe(NO_3)_2[/tex] is made up of the combination of iron and nitrate molecule.
In [tex]2Fe(NO_3)_2[/tex] compound, there are three elements which are iron (Fe), nitrogen (N) and oxygen (O).
The number of atoms of iron = 2
The number of atoms of nitrogen = 4
The number of atoms of oxygen = 12
Hence, the number of atoms of oxygen present in [tex]2Fe(NO_3)_2[/tex] are, 12.
