1.(a)Calculate the fugacity of pure methane vapor at T = 190.6 K and P = 32.2 bar.

(b) Using the Lewis fugacity rule, calculate the fugacity of methane in a mixture of 80 mol% methane and 20 mol% ethane at T = 190.6 K and P = 32.2 bar.

(c)What is the fugacity of pure liquid n-butane at 260 K at the following pressures: (a) 1 bar; (b) 200 bar. You may assume the density of liquid butane, 0.579 g/cm3, is independent of pressure
