What volume of oxygen gas $(O_{2})$ measured at $0^{0}$ C and $1$ atm, is needed to burn completely $1$ L, of propane gas $(C_{3} H_{8})$ measured under the same conditions?

$C_{3} H_{8} + 5 O_{2} ⟶ 3 C O_{2} + 4 H_{2} O$

$1$ mole of $C_{3} H_{8}$ requires $5$ mole of $O_{2}$

$∴ 1$ mole $= 22.4 d m^{3}$

$1 \times 22.4 d m^{3}$ propane needs $5 \times 22.4 d m^{3}$

$∴ 5 L$ of oxygen is required to burn $1 L$ of propane completely.

What volume of oxygen gas (O2) measured at 00C and 1 atm, is needed to burn completely 1L, of propane gas (C3H8) measured under the same conditions?

C3H8+5O2⟶3CO2+4H2O1 mole of C3H8 requires 5 mole of O2∴1 mole =22.4dm31×22.4dm3 propane needs 5×22.4dm3∴5L of oxygen is required to burn 1L of propane completely.
