Stoichiometry is one of the toughest fields to teach in Chemistry!
I have put together a worksheet, completely editable, that provides a wholesome summary of the different kinds of problems and rules to approach them.
This worksheet can be used as a group work assignment after the lesson is taught or as a tool to teach the lesson. Its an interactive worksheet that can cater the needs of advanced and not so advanced chemistry students. This handout can also be used as a study guide for a final review before a test or a quiz.
Some of the questions also come with answers!
