Vacuum Calculations
Today I finally got the voltage adaptor for my vacuum pump and turned it on. Not particularly exciting, and from the looks of things suitable neither
for reduced pressure distillations (too weak a vacuum) or for acting as the extractor unit in the fume hood I'm building (too little airflow).
The literature claims the pump produces a vacuum of 280mbar of mercury. How would I calculate the boiling point of water at this pressure so I can
test the pump experimentally?

Thanks. How do I convert mbar to torr?
Edit: Ignore that question. Converted it online, it's 210.

I think I can find a better plot for the temperatures near room temperature.

The single most important condition for a successful synthesis is good mixing - Nicodem
