You recall from your physics class that no individual gas has this value, but it occurs to you that you could produce a gas with =1.54 by mixing together a monatomic gas and a diatomic What fraction of the molecules need to be monatomic? My Answers Give Up Provide 80 F5 F9 3 4

Explanation / Answer

gamma valuue for monoatomic gas is = 5/3 = 1.667

fro diatomic gas is 7/5 = 1.4

fraction (f) = gamma mix-gamma dia/(gamma mono-dia)

f = 1.54-1.4/1.667-1.4

f = 0.524

52.4% is monoatomic and 47.6% diatomic gas
