Answer : The volume of 
 consumed are, 
 L.
Explanation :
The balanced chemical reaction will be:

First we have to calculate the moles of Al.

Molar mass of Al = 27 g/mole

Now we have to calculate the moles of 
.
From the reaction we conclude that,
As, 4 mole of Al react with 3 moles of 
So, 2 mole of Al react with 
 moles of 
Now we have to calculate the volume of 
 consumed.
As we know that, 1 mole of substance occupies 22.4 liter volume of gas.
As, 1 mole of 
 occupies 22.4 liter volume of 
 gas
So, 
 mole of 
 occupies 
 liter volume of 
 gas
Therefore, the volume of 
 consumed are, 
 L.
