The molar mass of a liquid is to be determined by evaporating a liquid at constant temperature and pressure, and measuring the volume of  vapour  formed using a calibrated gas syringe.


  • For both demonstration and student experiments
  • Simple procedure - fast results
  • Glass jacket system easily expandable


  1. Determine the molar masses of diethyl ether and methanol.
  2. Discuss the results in terms of the real and ideal behaviour of vapours.

What you can learn about
