What volume of propane is burnt for every 500 cm3 of air used in the reaction under the same conditions? (assuming oxygen is `1/5`th of air)

\[\ce{C3H8 + 5O2 → 3CO2 + 4H2O}\]

उत्तर

Volume of O2 in 500 cm3 of air = 20%

= `20/100 xx 500`

= 100 cm3

\[\ce{C3H8 + 5O2 → 3CO2 + 4H2O}\]
1 vol.      5 vol.

∴ Volume of propane burnt = `100/5`

= 20 cm3
