The minimum number of moles of $O_{2}$ required for complete combustion of 1 mole of propane and 2 moles of butane is..............

Answer:

18.00

Solution:

(1) Combustion of propane.

$C_{3} H_{8} + 5 O_{2} (g) \to 3 {CO}_{2} (g) + 4 H_{2} O 1 mole 5 mole$

(2) Combustion of butane

$C_{4} H_{10} + \frac{13}{2} O_{2} \to 4 {CO}_{2} (g) + 5 H_{2} O 1 mole \frac{13}{2} mole$

so total mole of $O_{2}$ $= 5 + 13 = 18$
