Agenda
- Given a target mass of product, work backwards to the reactant mass
- Run it — weigh out your own calculated amount and see what you get
- Compare predicted against actual across the room, significant figures kept
- Name it: Stoichiometry — the mole ratio as the step in the middle
- Practise: Stoichiometry Practice, in pairs, showing every step
Things to do before our next class
- Stoichiometry Practice, questions 1–8, showing the mole ratio step.
- Journal: where your prediction and your result parted company, and which of the two you trust more.
