# Calculating fugacity

1. Feb 2, 2008

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/" [Broken], and the approximate calculation for fugacity.

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