Agas sample has an initial pressure of 547 mmhg and initial volume of 0.500 l. pressure (in atm) when the volume of the sample is decreased to 225 ml?

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
