the vapor pressure of liquid bromoethane, c2h5br, is 100 mm hg at 263 k. a 0.309 g sample of liquid c2h5br is placed in a closed, evacuated 360. ml container at a temperature of 263 k. calculate what the ideal gas pressure would be in the container if all of the liquid bromoethane evaporated. mm hg assuming that the temperature remains constant, will all of the liquid evaporate? what will the pressure in the container be when equilibrium is reached? mm hg
