For the remainder of class, students worked through the Lesson 83 Worksheet. We began with Part A, in which students were tasked with determining which mystery solution matched with one of three chemical formulas. The mystery solutions each had a different mass, but all three were known to be 100 mL and 1.0 M solutions. Notes from the white board are provided below. For homework, students were assigned problems #1-8 from Lesson 83 in the textbook. Also, students were provided with a printed copy of the Chapter 15 Study Guide and were told about the revised schedule for next week (Chapter 15 quiz on Thursday).
