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