Lab-Determination of the Molar Mass of Volatile Liquid
Purpose: The purpose of this experiment is to determine the molar mass of a volatile liquid(ethanol) based on measurements of
its vapor density. The ethanol is volatilized and condensed in a fixed vol

Introduction
The term "infra red" covers the range of the electromagnetic spectrum between 0.78
and 1000 m. In the context of infra red spectroscopy, wavelength is measured in
"wavenumbers", which have the units cm-1.
wavenumber = 1
