Calculation Formula

Normality (N) = Molarity (M) × Number of Equivalents (n)

Where:
Normality (N): The concentration of the solution expressed as gram-equivalents per liter
Molarity (M): The concentration of the solution expressed as moles per liter
Number of Equivalents (n): The number of gram-equivalents of solute per mole of solute

How to Use the Normality Calculator

  1. Enter the Molarity (M) of your solution. This is the number of moles of solute per liter of solution.
  2. Enter the Volume (L) of your solution. Ensure this is in liters for accurate calculation.
  3. Enter the Number of Equivalents (n). This represents the number of gram-equivalents of solute per mole of solute.
  4. Click the Calculate button to compute the normality of your solution.
  5. The result will be displayed in the Normality (N) field.

Understanding Normality

Normality is a measure of concentration that is commonly used in acid-base chemistry. It is defined as the number of gram-equivalents of solute per liter of solution.

The formula for calculating normality is:

N = M × n

Where:

  • N = Normality
  • M = Molarity (moles per liter)
  • n = Number of equivalents

Example Calculation

For example, if you have a 2 M solution of H₂SO₄ (sulfuric acid) and you want to calculate its normality, you would use n = 2 because sulfuric acid is diprotic (it can donate 2 protons). The calculation would be:

N = 2 M × 2 = 4 N
