I am only 2 days in. Maybe I just feel nervous with what the semester has in store.
I am trying to knock out my lab data sheets so I am prepped for the year without having to stress getting it done the week before.
It feels self explanatory, but I feel doing it wrong. For example so many numbers thrown down not sure what numbers to write down. Then have to write out what needs to be recorded. Have to keep the firm correct and only use right pages.
Chemistry is one of those love it/hate it courses. Kind of like physics. It either clicks for you or you are just lost all semester. What is your major? And PittChick is right -- organic chemistry is double tough
I am doing good it's just conversions of nm to meters to cm that is getting me messed up. All I have to work off from notes, text, and slides is 10 to the power of 9 equals a gram.
So if I have 8.654 x 10 to power of 11 nm to convert it to cm our instructor wants us to convert it to meters. Then from meters to cm.
Where I cancel out the 8.654 multiplying it to 1 over 10 to the power of 9.
That give me .8654 to the power of -2 or 2 I get confused
Then I convert it to cm multiplying by 100 86.54 x 10 to power of 2 I believe. With a SF of 4.

Are you trying to convert from nm a unit of length to grams a unit of weight?

From nm to m to cm (not sure why anyone would since they are used for distinctly different physical scales) is just a matter of moving the decimal point. 1 nm = 0.000000001 m
Since it is early in the semester, maybe you should get a prep book and spend a weekend going over the basics of physics, science etc.
Your professor has office hours and many chemistry classes have a recitation section, which is like extra help. I bet your university has a tutoring center, too. Don't be shy about office hours - your professor would rather have you come in and say "I didn't totally understand the lecture, could I get some help with...?" than come in at the end of the semester in a panic or asking for extra credit. Sometimes all you need is a little extra explanation for it to click. I have two degrees in chemistry and went for a ton of extra help in organic because boy, I needed it. It's not forever, only a semester. Good luck!

Didn't you do this kind of calculation in high school chemistry/physics? Its at that level.

It's making me want to pull my hair out.
How can one knock out lab data sheets for the year without having the cumulative classroom teaching/lab experience to do so?
I'm old. I'm like, 45 years old.
Is this how it works in 2016?
One can just sit down and knock out labs that they have yet to been taught the basics to understand?
Maybe I am not understanding your issue, please correct me if I am not?
If I am not misunderstanding your issue, you might want to drop the class (it's early in the school year) and take a lower level chem class that will prepare you to sail through the first few weeks of the chem class you are currently enrolled in?
Whatever it is? Best of luck to you.
