A Level Mole Calculations
iOS Universel / Education
This A Level ad-free and subscription-free app automatically generates questions on the following topics: Avogadro's Constant, Relative Atomic Mass, TOF Mass Spectrometry, Mr and Percentage by Mass, Empirical Formula, Calculating Moles, Reacting Masses, Limiting Reagents, Percentage Yield, Atom Economy, Concentration of Solutions, Titration Calculations, Back Titrations, Water of Crystallisation, Gas Volumes, The Ideal Gas Equation (PV=nRT) and Redox Titrations. Five mini review tests are available to help check on progress once a number of topics have been attempted. The topics, and most importantly the questions within, have been carefully sequenced so that complexity increases as users progress through the chapters.
Features of the app:
1. The Amount of Substance page:
This provides an overview of all the topics in this app.
2, The Topic page:
The page gives access to the the "Practice" and "Quiz" features of the app (button left and button right respectively).
3. The Practice page:
Here several styles of questions on the chosen topic can be attempted. Markschemes are available along with a "Add to Favourites" button which can store questions if users want to review them later. These questions can be accessed in the Favourites section, on the Amount of Substance page. Questions from this list can be deleted by selecting the tab and swiping left. There is also a periodic table button which gives information about relative atomic masses of chemical elements.
4. The Quiz page:
The Quiz section allows users to test themselves once mastery is achieved. When the quiz is completed, users can review the markschemes and are offered feedback if the question is not completed correctly.
5. The Mini Review page:
Users can test themselves on questions from different topics in this section.
6. Automatic generation of questions:
The numbers for each question are automatically generated so this should allow users to continually practice their skills. New questions are generated each time a topic is selected.
The app has been tailored for post 16 examination boards but should suit anyone who is learning about mole calculations.
I hope you enjoy this app as much as I have enjoyed creating it!
Quoi de neuf dans la dernière version ?
Some minor bug fixes. The name of the app has been updated to increase visibility on the App Store.
