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.
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.
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.

Equivalent weight is used in the calculation of normality. The normality of a solution is defined as the number of gram equivalents of the solute present per litre of the solution. It is represented by the symbol, N. Normality = gram equivalent of the solute/volume of the solution in litres.
Definitions of Equivalent Weight ( Acid-Base Context ) The weight of a compound that contains ONE EQUIVALENT of a proton (for acid) or ONE EQUIVALENT of an hydroxide (for base). Examples: (1) H 2 SO 4 + 2OH - = 2H 2 O + SO 42-. Molecular weight of sulfuric acid (H 2 SO 4) = 98.07 g/mol.
