12 gm He and 4 gm `H_(2)` is filled in a container of volume 20 litre maintained at temperature 300 K. the pressure of the mixture is nearly :

A

3 atm

B

5 atm

C

6.25 atm

D

12.5 atm

Text Solution

Verified by Experts

The correct Answer is:
C
`PV=nRT`
`P=(nRT)/V =((12/4+4/2)xx8.31xx300)/(20xx10^(-3))=6.25 xx10^(6) Pa`
