This app contains all the sections required in the GCSE Chemistry mole calculations topic and is ad free. Topics include:
Avogadro's Constant, Molar Mass, Balancing Equations, Calculating Moles, Mole Ratios, Reacting Masses, Limiting Reagents, Concentration, Titration Calculations, Gas Volumes, Percentage Yield and Atom Economy.

For most topics the app generates questions automatically. Questions are rarely repeated upon relaunch of the app.

It also provides ample opportunity for practice in each of the twelve topics and keeps track of your progress as indicated by the coloured sections on the Main Menu page.

Each topic consists of a practice section with questions, hints and worked solutions. The quiz page allows users to test themselves once mastery is achieved.

Both of these section come with an inbuilt periodic table page which provide details of atomic numbers and relative atomic mass.
