Chem Help is an app to help with a regular to honors chemistry class. It can find the molar mass and percent composition of any compound you enter. It lists all the elements and their ion charges, properties, electron configurations, atomic numbers and atomic mass. It lists common polyatomics and their charges and formulas. It can convert between moles, grams, and atoms for different compounds. Also, it can give the hydrate formula when given the water mass, anhydrate mass and anhydrate formula and includes a simple calculator in the app so you don't need to switch around applications.
