CALCULATING ON THE SIDE OF SUCCESS – Module K(2025): REACTING MASS CALCULATIONS
K. STOICHIOMETRY & REACTING MASS CALCULATIONS
K1. STOICHIOMETRY INVOLVING MASSES & AMOUNTS
K1.1 TYPICALLY WORDED PROBLEMS
Commonly met stoichiometry problems present a certain quantity of a reactant and then ask how much of a particular product can be formed. A chemical equation,
To have a decent chance of enjoying sustained success in tackling stoichiometry problems like this it is necessary at the outset to be able to:
Unless one masters such techniques, attempts to apply them skilfully and so understand stoichiometry will, in general, be unsuccessful and certainly make inefficient use of time. And so these techniques should be addressed before beginning stoichiometry problems, not during or after the event.
