Question description

Hello there, this was a lab experiment. I have the data from the experiment which will be send to you. However, due to time restraints I can't complete the lab. I need someone to carefully go over each step. Answer every calculation and graph any data needed. Please make sure all questions are answered. Please use word document (nothing handwritten) if citing use ACS style, and for graph use excel only please. If you have any question let me know! The lab is from pg 48-51. Please check to see if the link is working! http://ars-chemia.net/Classes/102/manual/102_manua...

Please do questions 20-22 and 1-6. Use word document please, for graph use excel. Experimental data will be provided after I pick you!
