WBJEE · Physics · Kinetic Theory of Gases
If pressure of real gas \(\mathrm{O}_{2}\) in a container is given by \(\mathrm{P}=\frac{\mathrm{RT}}{2 \mathrm{~V}-\mathrm{b}}-\frac{\mathrm{a}}{4 \mathrm{~b}^{2}}\), then the mass of the gas in the container is
- A \(32 \mathrm{gm}\)
- B \(16 \mathrm{gm}\)
- C \(4 \mathrm{gm}\)
- D \(64 \mathrm{gm}\)
Answer & Solution
Correct Answer
(B) \(16 \mathrm{gm}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{P}=\frac{\mathrm{RT}}{2 \mathrm{~V}-\mathrm{b}}-\frac{\mathrm{a}}{4 \mathrm{~b}^{2}}\) \(\left[\mathrm{P}+\frac{\mathrm{a}}{4 \mathrm{~b}^{2}}\right]=\frac{\mathrm{RT}}{2 \mathrm{~V}-\mathrm{b}}\)…
