Formerly, the connotation of "mole" was "gram molecular weight". Current usage tends to apply the term "mole" to an amount containing Avogadro's number of whatever units are being considered. Thus, it is possible to have a mole of atoms, ions, radicals, electrons, or quanta. This usage makes unnecessary such terms as "gram-atom", "gram-formula weight", etc. 3, record 1, English, - mole
