9/16 Chemistry update and homework due 9/23

Hi folks,

Today we spent time going over some basic but important information dealing with using numbers in chemistry.  We discussed scientific notation, significant figures and we touched a bit on the concept of density.

Homework due next week is to:

Take a look at this website dealing with significant figures  http://www.chem.sc.edu/faculty/morgan/resources/sigfigs/

Do the problems at the end numbered 1-10 feel free to look at the answers once you've finished the problems

Also take a look at the enclosed .pdf.  

The page numbers are strange on this so do the problems on the page marked 55 in the upper right hand corner and the problems on the page marked 58 in the upper right hand corner.  Again, feel free to check your answers when you're done.  Remember though, this will be on next week's quiz so be sure you know how to do these problems.  If you get something wrong in the homework, know why.  It may come back to haunt you on the quiz.
