What have you done so far, and where are you having difficulty?  What have you learned recently in class, and how have you tried to apply it, and where has it gone wrong?  What does the beginning of the lab assignment offer to you in terms of calculations you can perform?

Please try to answer some of these questions on your own.  You listed 8 questions, have you done any of them?
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.
