The number of moles of aluminium  that are needed to react completely  with 13.2 moles of FeO  is  8.8 moles
calculation
2Al + 3FeO → 3aFe +Al2O3
by use of of mole ratio of Al: FeO  from  equation above = 2:3 the moles of  Al is  therefore
 = 13.2  x  2/3=8.8  moles  of Al

Answer:
 6.022 × 10²³ molecules of B₂H₆ 
Explanation:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
B₂H₆ molecules:
21.63 g = one mole of B₂H₆= 6.022 × 10²³ molecules of B₂H₆ 
 
        
             
        
        
        
Boyle's law gives the relationship between pressure and volume of gases.
it states that for a fixed amount of gas at constant temperature, pressure of gas is inversely proportional to volume.
PV = k
where P - pressure , V - volume and k - constant 
P1V1 = P2V2 
where parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
substituting this equation 
P x 0.5650 L = 715.1 bar x 1.204 L
P = 1 524 bar
        
             
        
        
        
This problem can be solved using Boyle's law:p1v1=p2v2
so 5.23*214=796*v2 v2=(5.23*214)/796=1.4L
