Normalty
This is for the chemistry teacher or lab assistant that needs to prepare solutions for an experiment. The “Normalty” or normality program is used to determine the amount of mls of concentrated acid or base required to prepare a desired volume, in L, for a wanted concentration of solution measured in normality. This program can also be used to prepare molar solutions by reading the note below. This program is designed for diluting acids or bases that have the measured percent concentration on the bottle and not in molarity, M.


This program will ask for the following information:
* “CONC N =”, the concentration you want to prepare measured in normality.
* “GEM or GEWT”, the GEM, gram equivalent mass or the gram equivalent weight, of the acid or base your preparing. 
* “Liters of solution”, the liters of solution you want to make or total volume of solution needed.
* “PERCENT CON”, the percent concentration of the concentrated acid or base you are planning to dilute.
* “DENSITY (G/ML)”, the density (g/mL) of the concentrated acid or base you are planning to dilute.

The answer shown on the screen, “mLs of solute required”, is the amount of concentrated acid or base needed to be diluted with water to make the desired volume of solution wanted in L.

Note: If you with to prepare a molar solution enter for “CONC N =” the molar concentration and where it asks for “GEM or GEWT” enter the molar mass or gram formula mass.

If you are using acids or base solutions from Flinn, you don’t need this program since they sell their solutions already in Molar, M; concentrations that are easy to dilute. You can use the formula concentration (1) x volume (1) = concentration (2) x volume (2).
