Question: An experiment you're designing needs a gas with gamma = 1.66. 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 gamma = 1.66 by mixing together a monatomic gas and a diatomic gas.
Question 1: What fractions of the molecules need to be monatomic?
