This Wednesday, April 27th, we will have a study session that focuses on problem solving with special emphasis on the following worksheet: Colligative Properties.
The session will begin at 2:00 PM. I will check for new arrivals at 2:30 PM and at 3:00 PM. I hope to see your there.
Also, because Chapter 14 is so desciptive, I am suggesting you go over the following questions to see if you can figure out the answers. The correct answers will be posted in a few days.
