Acid & Base Normality/Molarity Calculator

Look up the molarity and normality of common concentrated lab reagents, then calculate how much stock to dilute for a target concentration.

Reagent

Reference values (specific gravity, %assay) are typical for reagent-grade concentrated stock and can vary by manufacturer/lot — check your Certificate of Analysis for exact figures before precise work.
