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

$1 mole C_{3} H_{8} + 5 mole 5 O_{2} \to 3 C O_{2} + 4 H_{2} O$

For 1 mole propane combustion 5 mole $O_{2}$ required

$C_{4} H_{10} + \frac{13}{2} O_{2} n \to 4 C O_{2} + 5 H_{2} O$

1 mole 6.5 mole

2 mole 13 mole

For 2 moles of butane 13 mole of $O_{2}$ is required

total moles $= 13 + 5 = 18$
