Why do volatile liquids with lower boiling points give better results when deter
This is when the boiling points are compared to volatile liqiuds with higher boiling points.If you are using the method of determining the molecular weight that involves volatizing a small amount of the material in a flask closed with aluminum foil with a pin-hole in it; it is easier to do it with materials that evaporate easily as you can get it weighed before the liquid has condensed and pulls in a lot of air thus messing up the results.
