Answer: 
iron atoms
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number 
of particles.
![1 molecule of [tex]Fe_2O_3](https://tex.z-dn.net/?f=1%20molecule%20of%20%5Btex%5DFe_2O_3)
contains= 2 atoms of iron
![1 mole of [tex]Fe_2O_3](https://tex.z-dn.net/?f=1%20mole%20of%20%5Btex%5DFe_2O_3)
contains=
atoms of iron
thus 0.32 moles of 
contains=
atoms of iron
Thus the sample would have iron atoms.
