Moles and Quantitative Chemistry

Start with atomic structure

Begin with OCR AS Chemistry Flash Cards to review the terms used in several resources on this page. The deck includes atomic number, mass number and isotopes. Use the cards to check whether you can distinguish the number of protons from the total number of protons and neutrons.

Next, look at Chemistry - C2.3. This mind map brings atomic number and mass number together with the numbers of protons, neutrons and electrons. Moving between the cards and the map gives you a way to check individual terms and then see how they relate.

Move on to moles and quantities

The notes on atomic structure include relative atomic mass, relative formula mass and moles. After reviewing the particle terms, use these notes to follow the move from atomic structure to quantities. The notes created from a chemistry mind map also list atoms, ions, isotopes and moles, giving you another way to study those terms together.

A mind map on atomic structure, analysis and quantitative chemistry explains how relative atomic masses can be used to calculate how much can react and how much can be produced. Compare that point with the notes as you study the quantitative material.

Use maps and questions together

There are no quizzes listed on this page. With a free account, you can make your own quiz and use it alongside a mind map: turn a point from the map into a question, then return to the map to check your answer. The account also saves quiz scores.

Moles and Quantitative Chemistry is a section of the Atomic Structure unit in Chemistry. The resources here connect particle descriptions and atomic numbers with relative masses and moles. Choose a map or set of notes and follow that connection at your own pace.
