Question

To an evacuated vessel with movable piston under an external pressure of $1 atm ., 0.1 mol$ of Ne and 2.0 mol of an unknown liquid with a vapour pressure of 0.727 atm at $2 7^{\circ} C$ are introduced. Considering ideal gas behaviour, the total volume (in litre) of the gases at $27^{\circ} C$ is close to [Given $R = 0.082 L atm mol^{- 1}$ ]

Answer:

9

Solution:

$p_{N e} = 1 - 0.727 = 0.273 atm \Rightarrow 0.273 \times V = 0.1 \times 0.082 \times 300 \Rightarrow V = 9 L$

TestHub · Accepted Answer

p N e ​ = 1 − 0.727 = 0.273 atm ⇒ 0.273 × V = 0.1 × 0.082 × 300 ⇒ V = 9 L
