Consider the following apparatus. Calculate the partical pressure of He after opening the valve. The temperature is remain constant at `16^(@)C`
(a)0.164atm
(b)1.64atm
(c)0.328atm
(d)1atm

A

0.164 atm

B

1.64 atm

C

0.328 atm

D

1 atm

Text Solution

Verified by Experts

The correct Answer is:
a
(a)
`n_(He)=(1.2xx0.63)/(0.082xx289)," " n_(He)=(3.4xx2.8)/(0.0821xx289)`
`=0.032 " " =0.4`
`P_(f)=(0.431xx0.0821xx289)/(4.6)=2.223`
`P_(He)=(0.032)/(0.432)xx2.223=0.164atm`
