Answer

Explanation:

Step1: Identify mole - ratio

From the balanced chemical equation $\mathrm{Fe_2O_3}+2\mathrm{Al}\rightarrow\mathrm{Al_2O_3}+2\mathrm{Fe}$, the mole - ratio of $\mathrm{Fe_2O_3}$ to $\mathrm{Fe}$ is $1:2$.

Step2: Calculate moles of Fe

If $n(\mathrm{Fe_2O_3}) = 2.50\ mol$, and $\frac{n(\mathrm{Fe})}{n(\mathrm{Fe_2O_3})}=\frac{2}{1}$, then $n(\mathrm{Fe})=2\times n(\mathrm{Fe_2O_3})$. $n(\mathrm{Fe}) = 2\times2.50\ mol=5.00\ mol$

Answer:

$5.00$
