Struggling in your first chemistry class? Is stoichiometry too time-consuming and difficult for you? Or maybe you need to quickly calculate molar masses or convert between grams and moles.

ChemCalc is an all-in-one calculator and reference guide for high school and college chemistry. The app uses algorithms to calculate the molar mass of any chemical compound, with easy converting between grams and moles.

ChemCalc can also balance chemical equations using a complex matrix algorithm, allowing you to double-check your work and recognize reaction patterns.

On top of that, it'll do your stoichiometry for you in less than a minute! You can find the limiting reactant for a given reaction, the amount of excess reactant left, as well as the theoretical yield! Or, if you want to save time on your thermodynamics homework, enter an equation to calculate the enthalpy of any reaction in seconds!

Additionally, you can quickly search for element data, compound names and formulas, polyatomic ions, thermodynamic quantities, and acid/base dissociation constants.

More calculators and reference tables are in progress, and more can be added with your feedback! Download ChemCalc for free today.

What's New

Version 1.2

Added solubility product constants (Ksp) and standard electrode potentials to the More section! No more squinting at your textbook, just search for the value in the reference tables.

A must have for chemistry students

A Plus!

This is such an amazing tool for any level chemist. I’m in AP Chemistry currently, and this is such a huge help. I can quickly check my math with the stoichiometry function and the wide array of thermodynamic quantities are so helpful! No more scouring through my textbook! 😄



Best Spanish app I’ve ever used 10/10
Oh wait that’s the other one...this one was good too

amazing app
