Quantitative Chemistry workbook (Ar, Mr, isotopes, % by mass, Moles, Yield, Atom Economy)

I designed this workbook covering 5 lessons for year 11s starting C2.3 of the old AQA Chemistry course. Very little has changed with the new GCSE. I wrote it shortly before a period when I knew a lot of students would be missing, to allow them to quickly catch up. It contains a lot of worked examples (and I have also shown the working in the first few questions for each section in the answer booklet, which I hope non-specialists will find useful).

The booklet consists of worked examples and tiered questions for
- Relative atomic mass
- Isotopes
- Relative formula mass
- Percentage by mass
- Moles
- Percentage yield

Balancing equations, empirical formulae and atom economy are also included, but not tiered. (Generally I find either kids can do empirical formulae or they can't - there isn't really a way to make it easier or harder!)

For each section there is a Level 1, Level 2, Level 3 so that students in a mixed ability class could all find a suitable level.

The one thing that I haven't really done in this booklet is explain yield, as the way I teach that doesn't really lend itself to booklet form!
