DEAR MOHIT
What actually reacts with C2H2 is oxygen 

2C2H2 + 5O2--->4CO2+2H2O 
and then 
2n(C2H2)=5n(O2)
n=V/Vm 
2*V(C2H2)/Vm=5*V(O2)/Vm 

Vm is a constant, so we just cross it 
V(O2)=2/5V(C2H2) 

V(O2)=2/5* 8 = 3,2 litres 
21% of airs volume is O2
V(air)=V(O2)/0,21 

=3,2 / 0,21 
=15,24 litres

C2H2 + 5/2 O2 ---> 2 CO2 + H2O
1 volume of C2H2 gives 5/2 volume of O2,
therefore 8 L of C2H2 will give 5/2*8 = 20 L of O2
But air contains 21% oxygen,
So 20/21 is approximately equal to 100
