A sample of air is saturated with benezed (vapour pressure = 100 mm Hg at 298 K,750 mmHg 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=650 mm "of" Hg`
on compressing `P_(f)=Hg650xx3mm "of" Hg=1950mm Hg`
so `P_(T)=(1950+100)=2050mm "of" Hg`
