Product Description

Classic AP Requirement #3—Determination of the Molar Mass by Vapor Density

The molar masses of specific gases are found by comparing masses of equal volumes of gases at the same temperature and pressure. Oxygen gas is selected as a standard and molar masses are assigned from it. In Part 2, the molar masses of specific volatile liquids are determined in a microscale experiment and by use of the Ideal Gas Law. Students gain experience in handling gases, using the analytical balance, and in microscale chemistry procedures.

Complete for 24 students working in pairs.
