### How to Calculate Normality of a Solution - ThoughtCo

Sep 25, 2019· 36.5 grams of hydrochloric acid (HCl) is a 1 N (one normal) solution of HCl. A normal is one gram equivalent of a solute per liter of solution. Since hydrochloric acid is a strong acid that dissociates completely in water, a 1 N solution of HCl would also be 1 N for H + or Cl - …

### how to calculate equivalent wt of Na2CO3 and NaHCO3 .

Mar 31, 2008· Best Answer: For Na2CO3 there are two Na+ atoms to react with acids. Therefore in case of Na2CO3 equivalent weight is Molecular weight / 2. In the case of NaHCO3 there is only one Na+ to react with acids. (You can imagine that one Na of Na2CO3 has been used by an acid) Therefore equivalent weight is Molecular weight / 1, or molecular weight itself.
