Questions
A gaseous mixture consists of 16 g of helium and 16 g of oxygen. The ratio of the mixture is
detailed solution
Correct option is D
For mixture of gases, Cv = n1Cv1+n2Cv2n1+n2where C = f2R, f is degree of freedomand Cp = n1Cp1+n2Cp2n1+n2where Cp = (1+f2)RFor helium, n1= 4, f = 3For oxygen, n2 = 12, f =5 ∴ CpCv = 4×5R2+12×7R24×3R2+12×5R2 = 4729 = 1.62Talk to our academic expert!
