We Have A Winner...
Honors: I just tallied the results of the Math of Chem exam and there is a large chasm between the D and G period class averages.
Class average-
D: 90 (time to celebrate! There were three 100's and a 99!)
G: 81 (what up G? There were two 100's but this class average was dragged down by about 7 clearly unprepared students who failed badly; there were very few people at extra help before this test.)
Most of you wrote lucid and easy to follow answers: you used proper formulas, units with labeled/identified substances, attention to significant figures, and unit cancellation.
In your notes, ALL of the test problem types had been done multiple times with complete annotation and warnings about common errors. That is how math of chem works: from the class and hw examples, I just have to change the substances and the amounts used and I have a complete and thorough exam. As some of you have proven, you can get a 100 on any of these math of chem tests via practice/repetition.
Please prove that to yourself on your next stoichiometry test.
