Gram-molecular Weight
Related Category: Chemistry: General
amount of a molecular substance whose weight, in grams, is numerically equal to the
molecular weight of that substance. For example, one gram-molecular weight of molecular oxygen, O
2 (molecular weight approximately 32), is 32 grams, and one gram-molecular weight of water, H
2O (molecular weight approximately 18) is 18 grams. The term
mole is often used in place of gram-molecular weight. See
gram-atomic weight.
