You have a solution of two volatile liquids, X and Y. Pure liquid X has a vapor pressure of 410.0 torr and pure liquid Y has a vapor pressure of 150.0 torr at the temperature of the solution. The mole fraction of X in the vapor at equilibrium above the solution is 1.5 times the mole fraction of liquid X in the solution. What is the mole fraction of liquid X in the solution?

Shown below are six containers that contain various liquids. Blocks of various solids are suspended in the liquids by being hung from a supporting rod. All of these blocks are the same size, but they have different masses since they are made of different materials. All of the containers have the same volume of liquid but the masses of these liquids vary since the liquids are different. Specific values for the masses of the blocks and the liquids are given...
3. Liquids A and B form an ideal solution. At 25 °C, the vapor pressure of liquid A and B is 13.0 kPa and 26.0 kPa, respectively. The vaporization enthalpy of liquid A and B is 35.0 kJ mol and 15.0 kJ mol respectively. At what temperature do liquids A and B have the same vapor pressure?
A simple distillation is performed to separate liquids X and Y. Liquid X has a vapor pressure of 180 Torr at room temperature while liquid Y has a vapor pressure of 55 Torr. Which statement best describes the collected distillate? Note: the distillate is defined as the solution that is collected from the distillation process. It will be equal quantities of X and Y It will be enriched in X relative to the initial mixture It will be 100% pure...
Consider two empty containers A and B whose volumes are 10mL and 20mL respectively. 1mL of liquid water is put into each container and the temperature of each container is adjusted to 20°C. The gas pressure in container B, which still has some liquid water in it, is found to be 17 torr. How would the pressure in container A AND the amount of liquid water in container A compare to that of container B? Can someone please explain in...
