# How do you calculate the boiling point of a compound?

And the temperature and ambient pressure are recorded. Typically, for vacuum distillation, the pressure is reported in $\text{mm Hg}$. When the $\text{normal boiling point}$ is reported, the ambient pressure is $1 \cdot a t m$. 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.
