24 wrz 2024 · The mass of an acid or a base that will release or neutralize one gram molecule (mole) of hydrogen ion. A 1-mole solution of H2SO4 contains 2 gram equivalents. A thousandth of a gram equivalent weight is a millequivalent. See normal solution.
Figure out how to calculate an equivalent and how it relates to a mole. Rishi is a pediatric infectious disease physician and works at Khan Academy.
Gram equivalent weight = mass of 1 eq. of whatever substance you're talking about. Normality = # equivalents/L solution (eq./L). Normally this coincides with molarity, except for polyprotic things which is where this is more commonly used.
1 cze 2016 · The equivalent weight or gram-equivalent weight (Eq) of an element or compound is that weight in grams which combines chemically with one equivalent of another element or compound. The equivalent weight of HCl is its molecular weight, because this compound has 1 equivalent per mole and reacts with one equivalent of another compound.
Gram Equivalent Weight is used to measure the amount of a substance that can react with or replace a certain number of hydrogen ions or electrons. It is calculated by dividing the molar mass of the substance by its valence. On the other hand, Gram Molecular Weight is used to measure the mass of one mole of a substance.
The gram equivalent weight is the mass of a compound that would give you 1 mole of some species or 1 equivalent. Example: what is the gram equivalent weight of hydrogen in H2SO4? You would say well 1 mole of the acid would give me 2 equivalents of hydrogens, but I want 1 mole of hydrogens (1 equivalents).
