Normality & Molarity Calculator

This tool helps you to prepare an acid or base solution of specified Molarity (M) or Normality (N) from a concentrated acid or base solution.

Select acid or base:
Chemical formula:

Density: g/mL
Formula weight: g/mol
Weight percentage: % w/w
Desired final volume: mL
Desired concentration:
Calculated Volume (mL) of stock required
to prepare Desired Concentration:
Results based on your selection:

Your stock solution of Selected Acid or Base is calculated based on a specified density (g/mL), a formula weight (g/mol), and a concentration (% w/w).

To make the Desired Concentration solution, slowly add the Calculated Volume (mL) of your stock solution to deionized water (1/4 th of Desired final volume).

Adjust the final volume of the solution with deionized water.
