Experiment on Molar Gas Volume

Aim: The aim of this experiment is to find the volumes of hydrogen produced when different masses of magnesium ribbon is added to hydrochloric acid. These results are then used to find the molar gas volume (volume in one mol of any gas) and to produce a graph of the volume of gas against the number of moles.

Introduction:

The properties of a gas are-

 Gases have low densities, much less than liquids and solids

 Gases fill any container completely and uniformly, and do not have a fixed shape

 They are able to be compressed

 They exert a uniform pressure on all inner surfaces of a container

 They are able to diffuse with other gases easily and quickly

Through the knowledge of these properties of gases, a scientist called Avogadro gave a hypothesis that `equal volumes of all gases measured...
