Chemistry 111: Final Exam Topics
The final exam is comprehensive – covering the whole quarter. An approximate
breakdown is as follows:
Multiple Choice (160 points):
o Roughly 2/3 based on older material (Topics from Exams 1–3)
o Rest based on new material – Chapters 16, 17, 18
Lab – related question (short answer= 40 points):
o ½ (20 points) based on lab questions from Exams 1-3.
o ½ (20 points) based on the Titration & Beer’s Law labs.
