A gas made of a mixture of 2 moles of oxygen and 4 moles of argon at temperature T. Calculate the energy of the gas in terms of RT. Neglect the vibrational modes.

Explanation

`v=(n_(1)f_(1))/(2)RT+(n_(2)f_(2))/(2)RT`
f - Number of degrees of freedom
`f_(1)` - For diatomic gas = 5
`f_(2)` - For monoatomic gas = 3
`therefore v=(2xx5)/(2)RT+(4xx3)/(2)RT`
`=5RT+6RT`
`v=11RT`
