A 100 mL flask contained `H_(2)` at 200 Torr, and a 200 mL flask contained He at 100 Torr. The two flask were then connected so that each gas filled their combined volume. Assuming no change in temperature,total pressure is

A

300 Torr

B

66.66 Torr

C

150 Torr

D

133.33 Torr

Text Solution

Verified by Experts

The correct Answer is:
D
`n_(H2)=(pV)/(RT)=(20000)/(RT)rArrn_(He)=(pV)/(RT)=(20000)/(RT)`
`:." "n_(H2)+n_(He)=(40000)/(RT)`
Total volume = 300 mL
`p=(n)/(V)RT=(40000RT)/(RTxx300)=(400)/(3)=133.33" Torr"`
