Included Information: CHEM 1112 (Gen. Chem. 2 Lab)
The extent of the material included will be from General Chemistry 2 ONLY. There were only certain labs that needed to be completed in my course and they may differ from what your instructor requires. I will separate the Pre-Labs and Post-Labs for ALL the labs I completed. I apologize if the one you were looking for is not on here. Best of luck.
2021 Update: It's been nearly a decade since posting these labs! I have long since moved on from this course and college. I will leave these up here since it takes no effort to do so. With that being said, any issues or questions you may have might never be addressed by me (As I hardly ever check them), but maybe a fellow visitor might offer some guidance. Good luck in all of your endeavors!

ReplyDeleteYou don't have any formal lab reports? I'm looking for 14A
ReplyDeleteHey Drew, do you happen to have 23?
ReplyDeleteI'm sorry I do not have anything other than what is on here. My apologies.
DeleteLab 13 - The end calculations : It should be moles of solute times kilograms of solvent (not grams times grams).example - 0.062 moles/kg times .1558 kg = 0.00966 moles (of solute). Then molecular mass (grams/mole) of unknown substance = 0.245 grams/0.00966 mole = 25.5 g/m , if all other measurements are right ... I think that is correct.
ReplyDeleteHow did you get 9.1x10^-4 on your formal lab report 13?
ReplyDeleteDoes anybody have 19A? Lol it's soo long!
ReplyDeleteHey Drew,
