We question the usefulness of presenting molality in general chemistry. This unit creates confusion and has little application beyond molar mass calculations based on freezing point depression. To investigate which concentration units research chemists use, we tallied the units used in a single issue of the Journal of the American Chemical Society. Molarity based units were used most frequently, with 591 usages. Molality did not appear. The academic community should reconsider having molality within the general chemistry curriculum.
