A cylinder contains a mixture of \(5 \mathrm{~g}\) of \(\mathrm{N}_2\) and \(6 \mathrm{~g}\) of Ar gases. If the total pressure of the mixture of the gases in the cylinder is 30 bar, then the partial pressure of \(\mathrm{N}_2\) gas is
- A \(16.36 \mathrm{bar}\)
- B 0.545 bar
- C 30 bar
- D 0.180 bar
Answer & Solution
Correct Answer
(A) \(16.36 \mathrm{bar}\)
Step-by-step Solution
Detailed explanation
\(\begin{gathered}W_{\mathrm{N}_2}=5 \mathrm{~g}, W_{\mathrm{Ar}}=6 \mathrm{~g} \\ n_{\mathrm{N}_2}=\frac{5}{28}=0.18 \mathrm{~mol} \\ n_{\mathrm{Ar}}=\frac{6}{40}=0.15 \mathrm{~mol}\end{gathered}\)…
