Re: Significant Figure
I think it's always safe to know significant figures and plus I heard for Lavelle's class he emphasizes a lot on sig figs. So I recommend you to review them.

Re: Significant Figure
It would be ideal I heard you may lose points for incorrect significant figures.

Re: Significant Figure
Can someone post the exact rules for significant figures or does anyone know where I could find them?

Re: Significant Figure [ENDORSED]
If I remember correctly, if you took Chem 14A with Lavelle, or know someone who has the old course reader on them, there should be one/two pages in the front of the course reader that specifically highlights what he expects from us for sig.figs. Additionally, I think the maximum points that can get deducted from our quiz score for not having correct significant figures is 2 points.

Re: Significant Figure
Also, if you do not have the Chem 14A Course Reader and do not know anyone who has it, there is the same two pages about sig fig rules in our current Course Reader. It is on pages 122 and 123 immediately following the practice quizzes.

Re: Significant Figure
For rounding a number that ends in 5 (i.e 768.8465), round up iff the number preceeding 5 will become even and truncate iff the number preceeding 5 is already even
Ex. 0.98775 -> 0.9878
Ex. 0.98765 -> 0.9876
Ex. 0.98775 -> 0.9878
