GRAM MOLECULE Meaning and
Definition
-
A gram molecule, also known as a mole, is a fundamental unit of measurement used in chemistry to quantify the amount of a substance. It represents a fixed number of particles, specifically, Avogadro's number (approximately 6.022 x 10^23). A gram molecule is defined as the amount of a substance that contains the same number of entities as there are atoms in 12 grams of pure carbon-12 (12C) isotope.
In more technical terms, a gram molecule is the molecular weight of a substance expressed in grams. It allows chemists and scientists to scale up or down the quantity of a substance in a systematic and consistent manner. The purpose of introducing the concept of a mole is to facilitate comparisons and calculations involving atoms, molecules, and compounds.
To calculate the number of gram molecules in a given mass of substance, one must divide the mass of the substance by its molecular weight. For example, if the molecular weight of a compound is 100 grams per mole, a sample weighing 500 grams would contain 5 gram molecules of the compound.
The gram molecule is an essential concept in stoichiometry, which deals with the quantitative relationships between reactants and products in chemical reactions. It allows scientists to determine the amounts of substances involved in a reaction, as well as the theoretical yields and limiting reactants.

A weight of a substance expressed by a number of grams equivalent to its molecular weight; thus a g.-m. of hydrogen weighs 2 grams; of water 18 grams, the 2 H atoms having a molecular weight of 2 and the O atom one of 16.

Etymology of GRAM MOLECULE
The term gram molecule is not commonly used in contemporary scientific literature. However, it seems to be a combination of two terms: gram and molecule.
The word gram originates from the Late Latin gramma, meaning a small weight or a small amount. It was later borrowed into French as gramme before being incorporated into English.
On the other hand, molecule comes from the Late Latin molecula, which refers to a particle. It is derived from the Latin word moles, meaning a small mass or a small quantity.
Therefore, the etymology of the term gram molecule would essentially be a combination of the units of measurement gram and the concept molecule.
