In Fe(NO3)3, how many Fe atoms are there?

One, three N, and 9 O.

thank you

To determine the number of Fe (iron) atoms in Fe(NO3)3, you need to understand the chemical formula and the concept of subscripts.

Fe(NO3)3 is a compound made up of iron (Fe) and nitrate (NO3). The subscript attached to each element represents the number of atoms of that element in the compound.

In this case, Fe(NO3)3 indicates that there is one Fe atom. The subscript 3 after NO3 represents that there are three nitrate (NO3) groups.

Since each nitrate group contains one nitrogen (N) atom, we can determine that there are three N atoms in Fe(NO3)3. Additionally, each nitrate group also contains three oxygen (O) atoms. Therefore, there are a total of 3 (NO3) x 3 (O) = 9 O atoms.

So, in Fe(NO3)3, there is one Fe atom, three N atoms, and nine O atoms.

I hope this explanation helps! Please let me know if you have any further questions.
