Liquid hexane at 298 K and 1 bar has the following properties: thermal expansion coefficient () = 5.2x10-4 K-1 isothermal compressibility () = 17.5x10-10 Pa-1 molar volume (v) = 1.30x10-4 m3/mole critical temperature (Tc) =507 K critical pressure (Pc) =29.7 bar

NOTE : if you use scientific notation you must use upper case E for the exponent, e.g. 5.0E-3 = 0.0050

1. Calculate the change in molar volume if the pressure is increased from 1 bar to 30 bar at 298 K (m3/mole).

2. Calculate the change in molar entropy if the pressure is increased from 1 bar to 30 bar at 298 K (J/mole-K).
