C2H5 + 2.5 O2→2CO2 + H2O

for burning 1 mole of C2H5, 2.5 moles of oxygen is required 
so, 2.5 x 22.4 = 56000cm3 of O2

total required air = M
20% of air = 56000 cm3 of O2
20 M/100 = 56000 cm3 of O2
M = 56000 x 100/20 
= 280,000cm3

C2h2 + 5/202  = 2 co2 + h2O 

Burning of 1 mole of c2h2 requires 2.5 mole O2 

That means 2.5 x 22.4L = 56000 cm 3 o2 

Let total air required be M  

20% of air = 56000 cm3o2 

20 m/100 = 56000cm3o2 

M = 56000 x 100/20 = 280000 cm raise to power 3
