I have spent my time today on figuring out what is percentage yield and actual yield for chemistry. I get the idea about what it is about, but I still have trouble for caculating it. Not really any special things occur today. Mr.Daul is in school today, so it was pretty relaxed during english. I finished my worked quickly, and fell asleep quickly as well. Once again, today is cold.
