At \(\mathrm{T}(\mathrm{K})\), a gaseous mixture of \(\mathrm{H}_2\) and \(\mathrm{O}_2\) containing \(20 \%\) (weight/weight) of \(\mathrm{H}_2\) exerts a total pressure of 2 bar. What is the partial pressure of \(\mathrm{O}_2\) (in bar)?
- A 0.2
- B 0.1
- C 0.4
- D 0.6
Answer & Solution
Correct Answer
(C) 0.4
Step-by-step Solution
Detailed explanation
\(\mathrm{P}_{\text {total }}=2\) bar, \(\mathrm{P}_{\mathrm{O}_2}=\mathrm{x}_{\mathrm{O}_2} \mathrm{P}_{\text {total }}\) For \(100 \mathrm{~g}\) of this gaseous mixture, \(\mathrm{W}\left(\mathrm{H}_2\right)=20 \mathrm{~g}\), W( \(\left.\mathrm{O}_2\right)\)…
