Molarity to Normality Converter

Convert Molarity (M) to Normality (N) by entering the molarity and the equivalence factor (n).

Result

--- N

Molarity vs. Normality

Molarity (M) is the number of moles of solute per liter of solution.

Normality (N) is the number of gram-equivalent weights of solute per liter of solution.

Conversion Formula

Normality (N) = Molarity (M) × n

Where n is the equivalence factor (or valence factor), which depends on the reaction type:

  • For acids: n = number of H+ ions (e.g., HCl -> 1, H2SO4 -> 2).
  • For bases: n = number of OH- ions (e.g., NaOH -> 1, Ca(OH)2 -> 2).
  • For redox reactions: n = number of electrons transferred.

Example

To find the normality of 0.5 M H2SO4:

Since H2SO4 can donate 2 protons (H+), n = 2.

N = 0.5 M × 2 = 1.0 N
