Today we started with a short Quiz, then spent time on Lab 4B (all questions, all Follow-up Questions, Conclusion].  For conclusions, follow the guidelines on the pink Marking sheets, not the instructions in the text.  We also learned about Percent Composition, and did any 9 problems from # 44/45.  We finished with a brief intro to solutions and concentration.
