Molecular Weight Determination by an Improved Temperature-Monitored Vapor-Density Method.

Grider, Douglas J.; And Others

Journal of Chemical Education, v65 n7 p641-43 Jul 1988

Recommends determining molecular weights of liquids by use of a thermocouple. Utilizing a mathematical gas equation, the molecular weight can be determined from the measurement of the vapor temperature upon complete evaporation. Lists benefits as reduced time and cost, and improved safety factors. (ML)
