The Lesson 82 Worksheet called for students to work in groups to prepare salt solutions and work through the math to calculate the molarity of their assigned solution. Although we did not review it in class, the Lesson 82 PowerPoint is available for download.

Additionally, students are encouraged to practice observing the relationship between moles, volume, and molarity using the University of Colorado Molarity PhET simulation below:
