the volume will be directly proportional to mole
therefore interms of volume
volume of H2=.5m3
volume of CH4=.35m3
volume of co=.08m3
volume of C2H4=.06m3
equation
H2 + 1/2O2 -----H2O
CH4 + 2O2------CO2 + 2H2O
CO +1/2O2 ----CO2
C2H4 + 3O2 -----2CO2 + 2H2O
THerefore the volume of O2 required is =.25 +.7+.04+.06 m3
volume of air is.25 +.7+.04+.06 m3*100/21 =5m3
