To determine the molar mass of a gas from a knowledge of its weight temperature pressure and volume. Learn vocabulary terms and more with flashcards games and other study tools. The value that corresponds to a pressure in atm was chosen for this problem.

We may have recorded the temperature too long after the gas vapor was vaporized. Molar Mass of a Vapor Abstract The purpose of this experiment was to observe how changes in temperature and pressure affected the volume of a fixed amount of unknown gas. Thus would lead to a low number of moles and a low molar mass.

In the case of getting an artificially high experimental molar mass the reason to this would be similar to getting a low molar mass. Pressurepsi and temperatureC straight line. We also determined the molar mass of the unknown gas from knowing its mass temperature pressure and volume.
