What will be the molar specific heat at constant volume of an ideal gas consisting of rigid diatomic molecules?

Temperature of an ideal gas, initially at $27^{\circ}$C, is raised by $6^{\circ}$C. The rms velocity of the gas molecules will,

The rms speed of oxygen is $v$ at a particular temperature. If the temperature is doubled and oxygen molecules dissociate into oxygen atoms, the rms speed becomes

$3$ moles of a mono-atomic gas $(\gamma = 5/3)$ is mixed with $1$ mole of a diatomic gas $(\gamma = 7/5)$. The value of $?$ for the mixture will be
