A neat little chemistry aid that includes so far: a Molar Mass calculator (w/ Isotopes) and Chemistry reference sheets.
The reference sheets include equations, constants, ions, etc.
For many people, calculating molar mass is a hassle since you have to look at a periodic table and then punch it into a calculator to add. This app will ease that pain and allow you to calculate Molar Mass quickly and easily.
Enjoy this free little App! (Ported from Windows Phone 7 platform)
