The above message contained the following:

I belive the term "molality" is as well-known and well-defined to a
chemist as "termperature" is to a thermodynamicist. I certainly knew it
when I studied chemistry. I also believe any lack of understanding on
the part of a user would be quickly dispelled by a glance at the units
(e.g., "moles per kilogram").

The term "molarity" (which I also knew) is now, however, obsolete. The
replacement term is, apparently, "amount-of-substance concentration of
...". It has the same units as before (e.g., "moles per liter").
