Calculate average molar that capacity at constant volume of gaseous mixture contained 2 mole of each of two ideal gases `A(C_(v,m)=(3)/(2)R)` and `B(C_(v,m)=(5)/(2)R) :`

A

`R`

B

`2R`

C

`3R`

D

`8R`

Text Solution

Verified by Experts

The correct Answer is:
B
Average `C_(v,m)=(n_(1)C_(v,m_(1))+n_(2)C_(v,m_(2)))/(n_(1)+n_(2))=(2xx(3)/(2)R+2xx(5)/(2)R)/(2+2)=2R`
