The vapor pressure of liquid propyl amine, c3h7nh2, is 100. mm hg at 274 k. a sample of c3h7nh2 is placed in a closed, evacuated 557 ml container at a temperature of 274 k. it is found that all of the c3h7nh2 is in the vapor phase and that the pressure is 53.0 mm hg. if the volume of the container is reduced to 330 ml at constant temperature, which of the following statements are correct? choose all that apply.
1) some of the vapor initially present will condense.
2) only propyl amine vapor will be present.
3) no condensation will occur.
4) the pressure in the container will be 100. mm hg.
5) liquid propyl amine will be present.
