1.	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.
Answer» Solution :For two moles of diatomic nitrogen with no vibrational mode, `U_(1)=2xx5/2RT=5RT` For FOUR MOLE of MONATOMIC argon, `U_(2)=4xx3/2RT=6RT` Total ENERGY of the GAS, `U=U_(1)+U_(2)=5RT+6RT` U=11RT
