Did anyone have Intro Chem over 10+ yrs ago???

Published

Hi everyone! I hope you are all having a good week so far. I started my intro to Chem class this week (M/T) and so far so good. However, we mostly are talking about significant numbers, rounding, stuff like that.... my question is did we do this sort of stuff in chem 10 yrs ago? I had high school chemistry in the early 90's (gulp) and I took a college chem class about 10 yrs ago. I don't remember any of this stuff. I just remember atoms and electrons... something about shells, stuff like that. I was wondering if this sig fig stuff is new to chem within the last 10 yrs? Or if I just mentally blocked all of that out...LOL.

Just curious if anyone remembers.

TIA Take care!

Any introduction to chemistry class should have addressed significant figures, both in high school and in college. Whether yours did or not is hard to say but I'm certain that it was in your text book.

Yeah, significant figures are covered in all General Chem courses. Its a fairly annoying concept (IMO) but important to master in terms of recording data and doing conversions. Good luck!

No! I'm completely with you. My HS Chem class was almost 20 years ago and I feel somewhat intimidated. I'm sure it will be fine because I know I am teachable but I will definitely be utilizing the tutoring center to play catch up with these formulas and conversions. I have a fairly strong "math anxiety" so I have to keep telling myself that I can lean this stuff, I just haven't yet! ;)

Yup, that's me. I took Gen Chem I in 1993....I'm taking Gen Chem II here soon and am scared!!!
