Two moles of a monoatomic gas is mixed with six moles of a diatomic gas. The molar specific heat of the mixture at constant volume is :

Answer:

Solution:

For mixture of gases, we can write

$C_{v} = \frac{n_{1} C_{v_{1}} + n_{2} C_{v_{2}}}{n_{1} + n_{2}}$

$= \frac{2 \times \frac{3}{2} R + 6 \times \frac{5}{2} R}{2 + 6}$

$= \frac{9}{4} R$
