30 sty 2023 · Equivalent weight can be defined as the mass of one equivalent of a given substance that will combine with or displace a fixed quantity of the other substance. It is represented by ‘E’ and is equal to the ratio of molecular weight and the valency factor. Equivalent Weight \ (=\frac {\text { Molecular Weight }} {\text { Valency Factor }}\)
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.
Inside this combination of a quiz and worksheet, you can find out how well you understand the calculation of equivalent weight. Questions focus on the n number of equivalents for an acid, and...
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.
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.
1 lut 2024 · Follow these steps: Enter the molar mass of the substance. Enter the valence of the substance. Click the “Calculate” button to get the equivalent weight. Formula. The formula for calculating equivalent weight (EW) is given by: Example Solve. Let’s consider an example where we want to find the equivalent weight of sulfuric acid (H₂SO₄):
21 lis 2023 · The Equivalent Weight (EW) formula is: EW = Molar Mass / n number of equivalents. Where "n" number of equivalents is the quantity of charge depending on the substance. If the substance is...
