Two moles of helium are mixed with n mol...

Two moles of helium are mixed with n moles of hydrogen. If `(Cp)/(Cv)=(3)/(2)` for the mixture, then the value of n is :

A

`1`

B

`3`

C

`2`

D

`3//2`

Text Solution

Verified by Experts

The correct Answer is:
C
`(n+2)/((3)/(2)-1)=(2)/((7)/(5)-1)+(n)/((5)/(3)-1) implies 2n +4=5+(3n)/(2) implies n=2`.
