Physical Chemistry #3: Stoichiometry and Reacting Masses and Volumes (Slides and Student Led Tasks)

This lesson goes over the concept of stoichiometry and how to do stoichiometric calculations that involve the reactions of masses and volumes. This is lesson three in our physical chemistry series for Unit 1: Atoms, Molecules and Stoichiometry (from the Cambridge International AS Chemistry Curriculum (9701) 2019-2021 curriculum).

LESSON OBJECTIVE: To balance equations and perform calculations using the mole concept and stoichiometric relationships. Understand the concept of a titration.

LEARNING OUTCOMES (from the Cambridge AS Chemistry Curriculum 2019-2021):
1.5 Reacting masses and volumes (of solutions and gases)
a) write and construct balanced equations
b) perform calculations, including use of the mole concept, involving:
i) reacting masses (from formulae and equations)
ii) volumes of gases (e.g. in the burning of hydrocarbons)
III) volumes and concentrations of solutions
c) deduce stoichiometric relationships from calculations
