- Easily calculate Molarity, Total Solution Volume, Solute Mass, or Molecular Weight.
- Simply input three of the four variables and the fourth is calculated automatically.
- The units can be changed for Total Solution Volume, Solute Mass, or Molecular Weight.
- In-App purchase available to create and store compounds for quick access.
The Molarity Abacus is a simple and easy way to do molarity calculations. Simply input any three of the four variables and the fourth will be instantly calculated. Includes full help documentation on each screen.
The seven strong acids and eight strong bases are pre-configured in the app and can be selected from a list of compounds.
With an In-App purchase, you gain even more functionality allowing you to create and store compounds for repeated use. You name the compound, select the elements in it, set the number of atoms for each element, and the molecular weight is calculated automatically. The full periodic table is included and has been loaded with molecular weights and checked against publicly available sources on the internet. The element weights can be edited.
This product includes software developed by the OpenSSL Project for use in the OpenSSL Toolkit (http://www.openssl.org/)

No frills, easy to use molarity calculator
Great app; straight forward and very user friendly. Superior to other free molarity calcs: easier to navigate than sigma and less buggy than life. As a grad student the ability to store compounds comes in handy during lab work.
Great for lab work!
This app is great and easy to use! Love the create your own compound feature! Great for students and anyone doing lab work
Perfect for my needs
This app does exactly what I need it to do. It's very convenient to be able to save my own compounds for repeat use in calculations. I use it every day.
With Family Sharing set up, up to six family members can use this app.
