GRAM EQUIVALENT Meaning and
Definition
-
The term "gram equivalent" refers to a concept in chemistry that measures the amount of substance based on its chemical properties and its reaction with other substances. Specifically, it is a quantitative measure of the number of chemical equivalents of a particular substance present in a given sample.
A gram equivalent is defined as the amount of a substance that is equivalent to the molar mass of the substance divided by its valence. The molar mass is the mass of one mole of the substance, measured in grams, and the valence is the number of electrons that an atom of the substance can share or receive during a chemical reaction.
The gram equivalent is used in stoichiometric calculations, which involve determining the exact quantities of substances involved in a chemical reaction. By knowing the gram-equivalent weight of a substance, chemists can precisely predict the amount of reactants needed, the amount of products formed, and other related information.
To calculate the gram equivalent, the molar mass of the substance is divided by its valence. For example, if the molar mass of a substance is 60 grams and its valence is 2, the gram equivalent would be 60/2 = 30 grams.
In summary, a gram equivalent is a measure of the amount of a substance based on its molar mass divided by its valence. It is a vital concept in stoichiometry and is used to determine accurate quantities of substances in chemical reactions.

Etymology of GRAM EQUIVALENT
The word "gram equivalent" is primarily used in the context of chemistry and is related to the concept of equivalence.
The term "equivalent" itself comes from the Latin word "aequivalentem", which means "equal, equivalent". It is formed by combining "aequilis", meaning "equal", with "valentia", meaning "value, power".
"Gram", on the other hand, originates from the Late Latin word "gramma", which means "small weight". It is derived from the Greek word "gramma", referring to "something written or drawn", and is related to the verb "graphein", meaning "to write".
When combined, "gram equivalent" refers to the quantity of a substance that is chemically equivalent to one gram of hydrogen or an equivalent of any other compound. This term is used to express the reactivity or chemical valency of different substances in relation to each other.
