One mole each of a monoatomic, diatomic and triatomic gases are mixed

1.	One mole each of a monoatomic, diatomic and triatomic gases are mixed C_(p)//C_(v) for the mixture is
Answer» `1.40` 1.428 1.67 None of these Solution :`C_(v) = (((3)/(2) R + (5)/(2) R + (6)/(2)R))/(3) = (7R)/(3)` `C_(p) = (((5)/(2) R + (7)/(2) R + (8)/(2) R))/(3) = (10R)/(3)` `(C_(p))/(C_(v)) = (10)/(7) = 1.428`
