A Cylinder containing an ideal gas (0.1 mol of1.0dm3) is in thermal equilibrium with a large volume of 0.5 molal aqueous solution of ethylene glycol at its freezing point. If the stoppersS1andS2(as shown in the figure) are suddenly withdrawn, the volume of the gas in litres after equilibrium is achieved will be
(Given,Kf(water) = 2.0 K kgmol-1, R = 0.08dm3atmK-1mol-1)

Options:

Answer:
C
Solution:

ΔTf=Kf×i×m
ΔTf=2.0×1×0.5
ΔTf=1
273-Ti=1
Ti=272K
P=nRTV
P=0.1×0.08×2721
P=2.176atm
Apply Boyle's law
P1V1=P2V2
2.176×1=1×V2
V2=2.17
