When the pressure P is constant at 1 atm, the melting point of Br_2 is T_m = 265.95 K and its boiling point is T_b = 331.85 K. Br_2 is therefore liquid at 298 K and 1 atm but it also has a finite vapor pressure hence the property of both liquid and gas Br_2 can be obtained at at 298 K and 1 atm. Using a DeHoff equation and the thermodynamic table on D2L calculate the absolute molar entropy...
