Answer : The volume of  consumed are,
 consumed are,  L.
 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
 moles of 
Now we have to calculate the volume of  consumed.
 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
 occupies 22.4 liter volume of  gas
 gas
So,  mole of
 mole of  occupies
 occupies  liter volume of
 liter volume of  gas
 gas
Therefore, the volume of  consumed are,
 consumed are,  L.
 L.
