Half the point of the lab is to learn how to perform basic experiments and document their outcomes. If you missed the lab then you need to get with your instructor and see if you can perform a make-up lab. If you cannot, then you will most likely have to accept a zero or get help from another classmate who was there. In any case, there is very little we can do other than giving you the answers to this lab. Which would be cheating and is highly frowned upon here at PF.
