Calculating Fugacity of Freon-12 at 82.2C, 9.65bar

[tabasko]

I need to find the fugacity of freon-12 (Dichlorodifluoromethane) at 82.2C and 9.65bar, using a method that does not require critical data. I'm assuming we can find any other information to solve the problem, but I not sure where to start..

I suspect you should be able to find everything you need using the following website- http://webbook.nist.gov/chemistry/fluid/" , and the approximate calculation for fugacity.

\textsl{f}\approx\frac{P^2\overline{V}}{RT}

Those values are for liquids, and in my problem, we have a gas!

Oh really?
