1.	A gas mixture consists of 2 moles of oxygen and 4 moles of argon at temperature T. Neglecting all vibrational modes, the total internal energy of the system isA. `4 RT`B. `15 RT`C. `9 RT`D. `11 RT`
Answer» Correct Answer - D d. Total internal energy of systme `U_(o x y g e n) + U_(argo n) = mu_(1) (f_(1))/(2) RT + mu_(2) (f_(2))/(2) RT` [As `f_(1) = 5` (for oxygen) and `f_(2) = 3` (for argon)]
