Question

How do you calculate the boiling point of a compound?

Answer 1

In fact the boiling point of a material is measured.

Explanation:

And the temperature and ambient pressure are recorded. Typically, for vacuum distillation, the pressure is reported in `"mm Hg"`. When the `"normal boiling point"` is reported, the ambient pressure is `1*atm`. Sometimes you can find tables, sometimes useful, that extrapolate the boiling point recorded at one pressure to the boiling point you would observe at a different pressure.
