This is the second lesson in the Amount of Substance topic in Module 2 - Foundations in Chemistry.
The powerpoint covers empirical and molecular formula, relative molecular mass, hydrated salts and water of crystallisation.
The worksheets will help with empirical formulae calculations (there is a help sheet if needed for weaker students) however there is also a stretch and challenge task on Ions for higher ability students to complete to differentiate.
The practical activity helps bring together empirical formula and water of crystallisation but also helps prepare students for PAG 1.3 prior to them completing their first PAG.
