C) 0.800 mol

Explanation:

4Al + 3O₂ → 2Al₂O₃

In order to convert from moles of Al₂O₃ into moles of Al, we'll need to use the stoichiometric coefficients, using a conversion factor that has Al₂O₃ moles in the denominator and Al moles in the numerator:

0.400 mol Al₂O₃ * $\frac{4molAl}{2molAl_2O_3}$ = 0.800 mol Al

So the correct answer is option C).
