3 paź 2024 · The equivalent weight (EW) of a substance can be calculated using the formula: \ [ \text {EW} = \frac {\text {MW}} {\Delta E} \] where EW is the equivalent weight, MW is the molecular weight, and ΔE is the number of electrons gained or lost by one molecule.
The amount of substances that completely react with each other in the reaction is called equivalent weight in chemistry. While answering the question, what is equivalent weight? you should keep in mind that its definition depends on the two factors; the molar mass and valency factor of the compound. Equivalent Weight of Acid and base
Formula. The formula to calculate equivalent weight is: Equivalent Weight (EW) = Molecular Weight (MW) / ΔE. In this formula, the molecular weight is expressed in grams per mole, and ΔE represents the number of moles of reactive species per mole of the substance.
30 sty 2023 · Equivalent weight is the ratio of molecular mass and valence factor. It can be calculated by knowing the valence factor for acids and bases, which are the number of replaceable hydrogen and hydroxyl groups, respectively.

8 mar 2020 · The general number of equivalents formula is. E = MW/charge number. Where MW is the molecular weight of the compound and charge number is the number of proton- or hydroxide-equivalents the compound contains. Examples with different acids and bases help illustrate how this works in practice.
