[CHM 111] Ranges on Prelab Answers

[Andrew J. Pounds]

Students -- I was asked yesterday about the ranges on the prelabs.  When 
you complete a prelab it will generally (but not always) show you the 
correct answer with a range.  For example

0.0022 ± 10%

or

8.72 ± 0.01


YOU DO NOT HAVE TO ENTER THE RANGE (± 10% or ± 0.01 PART).   For every 
prelab exercise involving calculations I determined the range or 
possible correct answers based on your correct handling of significant 
figures.   You get the points if your answer is in the range.  For 
example on the second example above you would have gotten the problem 
correct if you entered 8.71, 8.72, or 8.73.
