How to Convert Normality to Grams per Litre: A Simple Guide

Learn the step-by-step method to convert normality (N) to grams per litre (g/L) for various solutes.

141 views

To convert from normality (N) to grams per litre (g/L), you need to multiply the normality by the equivalent weight of the solute (in grams). The formula is: g/L = N * equivalent weight. For example, to convert 1N HCl (Hydrochloric acid) to g/L, you use its equivalent weight (36.46 g/mol), resulting in 36.46 g/L.

FAQs & Answers

  1. What is normality in chemistry? Normality (N) is a measure of concentration equivalent to the molar concentration multiplied by the number of equivalents of solute.
  2. How do I find the equivalent weight of a substance? The equivalent weight is calculated by dividing the molecular weight of the compound by the number of moles of reactive units.
  3. Can you give an example of a normality to grams per litre conversion? Yes, for 1N HCl, the equivalent weight is 36.46 g/mol, thus it converts to 36.46 g/L.
  4. Why is it important to convert normality to grams per litre? Converting normality to grams per litre helps in preparing precise chemical solutions in laboratory practices.
