Molarity Calculator

Molarity Calculator


The Molarity App from Sigma-Aldrich(R) is a chemistry calculator tool that generates lab-ready directions describing how to prepare an acid or base solution of a specified molarity or normality from a concentrated acid or base solution. A second tab includes a general molarity function that calculates the mass of any reagent needed to prepare a given volume of solution of desired molarity. A third tab features a stock dilution function that calculates how to dilute a stock solution of any known molarity to your desired volume and molarity.

Features:

● Calculates molarity and normality for common commercial acid and base solutions by auto-populating density, formula weight and weight percentage.
● Users may input lot-specific certificate of analysis values for density and weight percentage.
● The Acid and Base instructions link to Sigma-Aldrich website/mobile website to display relevant acid or base products.
● General molarity and solution dilution options feature molar, millimolar, micromolar, picomolar and femtomolar concentration options.
● The Android version includes option to save and share acid and base solution preparation instructions.

Notes:

Normality calculations assume reactions based on H+ or OH- ions.
Concentration of 56.6% ammonium hydroxide is equivalent to 28% ammonia (NH3).
Additional calculation details may be found with online web version at http://www.sigmaaldrich.com/molarity.

Recent changes:
● Now includes language support for English, Chinese, Japanese, Spanish, French, Korean, Italian and German.
● Enabled the ability to install app on external SD card.

Needs updates Need to have a molarity claculation based on mass too

Great, but needs precision options. Very useful and reliable, but really needs configurable precision. It's not hard to implement, and will get you the last star!
