19 kwi 2024 · The Equivalent Weight of a compound is the result of dividing the molecular weight by the charge number of that compound. E = Molecular Weight / n-factor (charge number) where, E is Equivalent Weight. Charge number indicates how many protons or hydroxide-equivalents the compound has.
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...
The equivalent masses of acids, bases, and salts are calculated as follows: Equivalent mass of an acid = molecular mass of the acid/basicity. Equivalent mass of a base = molecular mass of the base/acidity. Equivalent mass of a salt = molecular mass of the salt/total positive valency of metal atoms.
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.
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 formula to calculate equivalent weight is: Equivalent weight = Atomic weight / Valence For example, the equivalent weight of sulfuric acid (H2SO4) is calculated as follows: Equivalent weight = Molecular weight / Acidic hydrogen ions Equivalent weight of H2SO4 = 98 / 2 = 49 So, the equivalent weight of sulfuric acid is 49 g/equivalent.
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.
