Question

Liquid benzene $(C_{6} H_{6})$ burns in oxygen according to the following equation:
$2 C_{6} H_{6} (l) + 15 O_{2} (g) \to 12 C O_{2} (g) + 6 H_{2} (g)$
How many litres of oxygen at STP are required for the complete combustion of $117 g$ of liquid benzene?

Solution

The correct option is D 252 L
The given reaction is,
$2 C_{6} H_{6} (l) + 15 O_{2} (g) \to 12 C O_{2} (g) + 6 H_{2} (g)$

As per the reaction, 2 moles of benzene react with 15 moles of $O_{2} = 15 \times 22.4$ L of $O_{2}$
1.5 moles of benzene will react with = $\frac{15 \times 22.4}{2} \times 1.5 L = 252 L$
