What is the amount of water formed by combustion of \(1.6 \mathrm{~g}\) methane?
- A \(6.2 \mathrm{~g}\)
- B \(3.2 \mathrm{~g}\)
- C \(3.6 \mathrm{~g}\)
- D \(16 \mathrm{~g}\)
Answer & Solution
Correct Answer
(C) \(3.6 \mathrm{~g}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{CH}_4+2 \mathrm{O}_2 \rightarrow \mathrm{CO}_2+2 \mathrm{H}_2 \mathrm{O}\)
\(\frac{1.6}{16}=0.1 \mathrm{~mol}\)
Moles of \(\mathrm{H}_2 \mathrm{O}\) formed \(=0.2 \mathrm{~mol}\)
Mass of \(\mathrm{H}_2 \mathrm{O}\) formed \(=0.2 \times 18=3.6 \mathrm{~g}\)
\(\frac{1.6}{16}=0.1 \mathrm{~mol}\)
Moles of \(\mathrm{H}_2 \mathrm{O}\) formed \(=0.2 \mathrm{~mol}\)
Mass of \(\mathrm{H}_2 \mathrm{O}\) formed \(=0.2 \times 18=3.6 \mathrm{~g}\)
