Mole calculation is one of the challenging topics for those studied chemistry in secondary schools. Most students want extra exercise in order to get familiar with the relationship between reacting masses and the number of mole of particles. This app provides a channel for students to have self-checking in handling those questions after lessons and share their findings to their peers.
Using our custom keyboard, you can input formula of all compounds for mole calculations. Our apps can also provide result for the percentage by mass of different elements in the compounds.
