Chemistry - Real Gas Question with Solution | TestHub

If $P_1$ is the pressure of gas in bulb A with volume $V_1$, and $V_2$ is the volume of bulb B, then the initial moles of gas in vessel A initially = moles of gas in vessels A and B finally.

$$\frac{P_1{V}_1}{T_1}=\frac{P_f(V_1+V_2)}{T_f}(i)$$

The final pressure, $P_f$, is related to the initial pressure, $P_1$, as:

$$P_f=\frac{40}{100}{P}_1=0.4P_1(ii)$$

From equations (i) and (ii), and using $V_1=100c{m}^3$ and $V_2=150c{m}^3$:
