1. 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.
2. Determine the fugacity of pure liquid acetone at 100 bar and 382 K. The molar volume of the liquid is 73.4 cm3/mol. You may assume vi does not change with pressure.
3. Calculate the fugacity of pure liquid propane at 333 K and 22 bar.
4. Determine the fugacity of pure water at 25°C and 500 bar. State any assumptions that you make.
