Attached is the information from Lab#1 in Chemistry 121.  I've completed some steps and have question marks by the ones that I need help with answering.  Please DO NOT JUST PROVIDE the answer.  I need STEP by STEP instructions on how you arrive at the answer.   Need step by step answers to the questions by Sunday, September 25.  #6 is not marked with a question mark and I need help with it too.  Thank you, Natalie
