Converting Moles Between Substances: A Two-Step Guide

In this lesson from Unit 7: Rules of Numbers—Molesanity, we will explore how to convert moles of one substance to moles of another using two-step conversions. Students will engage in practical exercises that illustrate mole-to-mole conversions through real-world applications, like cooking recipes. The lesson is structured with an introduction, mini-lesson, practice examples, and a conclusion. Students will practice conversion problems such as calculating moles of sodium produced from sodium hydroxide and determine the grams of products formed in reactions.
