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 —Equivalent weight, EW, may be thought of as the mass of metal in grams that will be oxidized by the passage of one Faraday (96 489 6 2 C (amp-sec)) of electric charge. (More information can be obtained from the ASTM) Pure Element: EW = W / n. W = Atomic weight of the element.
