I got 0,666 mol

write the equation of the reaction and balnce it
4 $F e$ $Fe$ (s) + 3 $O_{2}$ $O_2$ (g) $\to$ $->$ 2 $F e_{2} O_{3}$ $Fe_2O_3$ (s)
If you have problems with balancing this chemical equation, here is the whole process explained:
put iron and oxygen [the reactants] in ratio to extract the number of moles for oxygen
On the picture below you can see how to work it out.
