Total pressure observed after opening the stopcock is [neglecting the volume of the tube connecting the two bulbs]

A

1.33 atm

B

3 atm

C

0.3 atm

D

0.75 atm

Text Solution

Verified by Experts

The correct Answer is:
A
Total initial moles = final moles.
`(0.1 xx 2)/(RT) + (0.2 xx 1)/(RT) = (P xx 0.1)/(RT) + (P xx 0.2)/(RT)`
`implies P = (0.4)/(0.3) = 1.33 atm.`
