`A` sample of air is saturated with benzene (vapour pressure `=100mm Hg` at `298K`), `750mm Hg` pressure. If 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
