Q. How much volume of oxygen at $STP$ , in litre is required to burn $4 g$ of methane gas completely?

$11.2$

$5.6$

$2.8$

$8$

At STP, $∵$ For the combustion of $16 g C H_{4},$
oxygen Required $= 2 \times 22.4 L$
$∴$ For the combustion of $4 g C H_{4},$
oxygen required will be
$= \frac{2 \times 22.4 \times 4}{16} L$
$= 11.2 L$
