Well a number you have to know is 6.02 x 10^23. That is how many atoms there are in a mole.

So if you have 1.81 x 10^24 atoms,
you divide that by 6.02 x 10^24 moles to get 3 moles

Using factor/label method:
1.81 x 10^24 atoms * 1 mol
------------------------ = 3 moles
6.23 x 10^23 atoms
(As you can see, the unit "atoms" cancels out from the top and bottom.)

The reaction that has been occurred will be $\rm 2\;Fe\;+\;Al_2O_3\;\rightarrow\;2\;Al\;+\;Fe_2O_3$ .

The chemical reaction has been defined as the interaction of the reactant molecules for the formation of the product. The changes have been taken place in the reactivity series and under specific conditions.

<h3>Reaction occur</h3>

The displacement reaction has been taken place based on the reactivity series. The more reactive element has been able to displace the less reactive element in the compound and form a new compound.

The following reactions have been analyzed as:

$\rm 2\;NaBr\;+\;I_2\;\rightarrow\;2\;NaI\;+\;Br_2$

In the reaction, Br has been replaced by Iodine. The iodine has been less reactive than Br and thus will not form the compound.

Thus, this reaction will not occur.
