Question

air contains nearly 20% oxygen by volume. The ratio by volume of oxygen to air at STP required for complete combustion of 20 gram benzene is

Answer 1

Answer:

2C2H2+5O2⟶4CO2+2H2O

From stoichiometric calculations:

2 C2H2

moles will react with 5 molecules of oxygen

1 C2H5⟶5/2 moles of O2

22.4 l C2H2⟶ 5/2×22.4 l of O2

1 volume of air -> 0.2 (20/100) volume of oxygen

Now the only thing I don’t know is how to convert the volume into liters so that I can find the correct answer.
