WebFor hardness calculations, equivalents are based on charge (eg. 2=2 for Ca) Eg. EW Ca = 1O0g/mol CaCO3 * 1 mol Ca2+12 eq = 50 g/eq as CaCO3 Alkalinity: Alkalinity is the measure of acid-consuming species (e.g. CO/', HCO3'); therefore, determine the equivalent weight of CaCO3 based on the number of H+ equivalents that can be consumed b) WebMar 8, 2024 · 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 … WebCa(HCO3) molecular weight.
