A sample of air is saturated with benzene (vapour pressure =100 mm Hg at 298 K) at 298 K, 750 mm Hg pressure.If it is isothermally compressed to one third of its initial volume, the final pressure of the system is

A

2250 torr

B

2150 torr

C

2050 torr

D

1950 torr

Text Solution

Verified by Experts

The correct Answer is:
C
Pressure of air =750-100=650mm of Hg
on compressing `P_f=650xx3` mm of Hg
=1950 mm of Hg
So, `P_T=(1950+100)=2050` mm of Hg
