I know I'm new and all but these equations don't seem THAT difficult compared to others posted.  I just want to make sure I did everything correctly so I can stop worrying about this exam and have a good weekend.  PLEASE any help is  much appreciated.  I'm sure once I get more advanced in chemistry I will help people in my situation.  Please help ease my mind.  Thank you so much ahead of time.
