Molecular weight determination by an improved temperature monitored vapor density method

“…Several methods for determining the molecular weights of volatile (1-4) and nonvolatile (5, 6) liquids are found in undergraduate laboratories. Two methods employ freezingpoint depression (1) or surface tension (5). The others involve a manipulation of the ideal gas equation, PV = nRT = g/MRT (1) where M is the molecular weight, R the gas constant, P the barometric pressure, T the absolute temperature, V the volume of the container, and g the mass of the vapor in the container.…”
