Principle
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.
Benefits
- For both demonstration and student experiments
- Simple procedure - fast results
- Glass jacket system easily expandable
Tasks
- Determine the molar masses of diethyl ether and methanol.
- Discuss the results in terms of the real and ideal behaviour of vapours.
Learning objectives
- Ideal and ordinary gases
- Equations of state for ideal gases
- Gas volumetry
- Determination of molar masses according to the vapour density method (Victor Meyer)
