What quantity of oxygen is required for complete burning of \(15.6 \mathrm{~g}\) benzene?
- A \(75 \mathrm{~g}\)
- B \(88 \mathrm{~g}\)
- C \(48 \mathrm{~g}\)
- D \(64 \mathrm{~g}\)
Answer & Solution
Correct Answer
(C) \(48 \mathrm{~g}\)
Step-by-step Solution
Detailed explanation
\(\begin{aligned} & \mathrm{C}_6 \mathrm{H}_6+\frac{15}{2} \mathrm{O}_2 \rightarrow 6 \mathrm{CO}_2+3 \mathrm{H}_2 \mathrm{O} \\ & \frac{15.6}{78}=0.2 \mathrm{~mol} \\ & 1.5 \mathrm{~mol} \times 32 \\ & =48 \mathrm{~g}\end{aligned}\)
