• Resumen

  • A recent paper by G. Marin-Puga, M. Guzman L., and F. Hevia [J. Chem. Educ. 1995, 72, 91] attracted my attention. A wrong regression formula was used in the paper to determine the vaporization enthalpy. The expression for the proportionality constant that relates the absorbance of the vapor with the vapor pressure was also wrongly derived. This prompted me to submit this short paper to clarify both points.
