Molarity for Pc

1. 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.

2. - Calculates molarity and normality for common commercial acid and base solutions by auto-populating density, formula weight and weight percentage.

3. 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.

4. 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.

5. - General molarity and solution dilution options feature molar, millimolar, micromolar, picomolar and femtomolar concentration options.

6. - The iPad version includes option to save and email acid and base solution preparation instructions.

7. - The Acid and Base instructions link to Sigma-Aldrich website/mobile website to display relevant acid or base products.

8. - Users may input lot-specific certificate of analysis values for density and weight percentage.

9. Normality calculations assume reactions based on H+ or OH- ions.

10. Concentration of 56.6% ammonium hydroxide is equivalent to 28% ammonia (NH3).
