MCQ
If isobutane and n-butane are present in a gas, then how much oxygen should be required for complete combustion of $5 \,kg$ of this gas ............ $\mathrm{kg}$
- ✓$17.9$
- B$9$
- C$27$
- D$1.8$

Answer
Correct option: A.
$17.9$
a
(a) Isobutane and $n-$butane $\left[ {{C_4}{H_{10}}} \right]$ have same molecular formula;
(a) Isobutane and $n-$butane $\left[ {{C_4}{H_{10}}} \right]$ have same molecular formula;
${C_4}{H_{10}} + \frac{{13}}{2}{O_2} \to 4C{O_2} + 5{H_2}O$
For $58\,gm$ of ${C_4}{H_{10}}$ $208 \,gm$ ${O_2}$ is required then for $5\, kg$ of ${C_4}{H_{10}}$
${O_2} = \frac{{5 \times 208}}{{58}} = 17.9\,kg$
