gram-molecular weight

   Also found in: Dictionary/thesaurus, Medical, Wikipedia 0.01 sec.
gram-molecular weight, amount of a molecular substance whose weight, in grams, is numerically equal to the molecular weight molecular weight, weight of a molecule of a substance expressed in atomic mass units (amu). The molecular weight may be calculated from the molecular formula of the substance; it is the sum of the atomic weights of the atoms making up the molecule.

 of that substance. For example, one gram-molecular weight of molecular oxygen, O2 (molecular weight approximately 32), is 32 grams, and one gram-molecular weight of water, H2O (molecular weight approximately 18) is 18 grams. The term mole mole, in chemistry, a quantity of particles of any type equal to Avogadro's number, or 6.02×1023 particles. One gram-molecular weight of any molecular substance contains exactly one mole of molecules.

 is often used in place of gram-molecular weight. See gram-atomic weight gram-atomic weight, amount of an atomic substance whose weight, in grams, is numerically equal to the atomic weight of that substance. For example, 1 gram-atomic weight of atomic oxygen, O (atomic weight approximately 16), is 16 grams. See gram-molecular weight.
