find the balanced equation

What pressure will be exerted by 0.675 moles of a gas at 25*c if it is in a 0.750-l container?

The excretory system,need answers for all: )

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.
