HON CHEMISTRY – So which is more important, accuracy or precision? Good question! Here’s the lecture from Monday on just that. Don’t lose that percent error formula – you’ll use it all year!
And then, drum roll please, just what you’ve been waiting for – your first intro into significant figures! Go on, be happy!!
i was looking for the answers in the back of the book and couldn’t find them. can anyone help?
Anyone……??
Andrea – I double checked and found that in this new edition of the book there are only answers to some of the practice problems within the chapter. They are in the back of the book on the purple reference pages – starting around R119.
if the number is 78.30 is the zero a sig fig?
Andrea – It’s a trailing 0 and there is a decimal, so……?
Sig figs were always pretty easy, so I’m looking forward to this lesson! Also, if you have, say, 0.15 L and you need to round it to one significant figure, would you start at the zero or the one? I’m pretty sure it’s one, but I’m not positive.
Sonal – You’ve got it! Start counting at the first number that’s significant.
