[CHM 371] Hints for Error Propagation Worksheet

[Andrew J. Pounds]

  By now many of you have hopefully completed the first three problems 
on the error propagation worksheet I gave you last Wednesday.  Somebody 
asked me the other day what kind of numbers you should expect.

Well, for number 2, the enthapy of vaporization for ammonia should be 
around +23 kJ/mole.  Your actual error analysis will determine how many 
decimal places are warranted.

In the case of the problem 3, the vibrational contribution to the heat 
capaticy for water should be around 1.8 J/deg-mol.   Again, your error 
analysis will determine how many decimal places you can use.

Let me know what questions you have.
