help with example 9.5

Postby Miya Eberlein 1J » Wed Jan 20, 2016 5:26 pm

Where did the Cv,m value of 12.47 J/K*mol come from in Step 2 of example 9.5? Is that something we can look up or was it calculated somewhere..?

It looks like that Cv value is incorrect, because it is for oxygen gas, which is linear, diatomic, so the Cv should be (5/2)*R=20.785 J/(mol*K), rather than the (5/2)*R value that they used.
