Note that rounding errors may occur, so always check the results. This time, the solute has a valence of 2, as NaCl separates into Na + and Cl-. HCl and NaOH react and produce NaCl and water as products. ›› NaCl molecular weight. * A link is available to convert Chlorine (Cl) to Table salt (sodium chloride) (NaCl). What is the normality of 25 grams of NaCl in 300 ml of diluent? equivalent weight of H 2 = E = Atomic weight / valence = 1 g mol-1 / 1 = 1 g mol-1. M molecular/equivalent weight of NaCl or Cl F1 0.1; conversion factor for % (*100/1000) W weight of the sample in grams F2 1 The result is calculated as mol/L and can be automatically transferred to the exchangeable unit WA 20. e.g. For example, the reaction between H C l \ce{HCl} H C l and N a O H \ce{NaOH} N a O H gives rise to N a C l \ce{NaCl} N a C l in the following manner: H C l + N a O H → N a C l + H X 2 O. 4 5 6 g of a metal gives 0 . The SI base unit for amount of substance is the mole. Also why is the equivalent per mole for CaCO 3 2eqv/mole? This tool converts Table salt (sodium chloride) (NaCl) to Chlorine (Cl). Equivalent weight, in chemistry, the quantity of a substance that exactly reacts with, or is equal to the combining value of, an arbitrarily fixed quantity of another substance in a particular reaction. Equivalent weight is the (mass of) number of moles of one reactant in a balanced reaction (or product) divided by the number of moles of another.
