Stoichiometry and Yield Lesson Set
Use the stoichiometry topic page, the compact starter track, one percent-yield checkpoint, and the solutions-and-pH topic page so chemistry quantities stay bounded and teacher-usable.
This lesson set is for the moment when chemistry needs a tighter quantity-and-output branch without widening into a giant subsystem. It starts with the stoichiometry-and-yield topic page for orientation, uses the authored starter track for the main order, closes with the percent-yield checkpoint already attached to that track, and then points to the solutions-and-pH topic page so the next chemistry branch stays visible.
