螢幕截圖 2016-04-05 13.39.28

Item no.: P3010501

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.

Tasks

  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

  • Ideal and ordinary gases
  • Equations of state for ideal gases
  • Gas volumetry
  • Determination of molar masses according to the vapour density method (Victor Meyer)

Necessary accessories

  • Precision balance 620g/0.001g
