The cusp of the Labor Day weekend...

There is (was?) a problem with the time in OWL, it has been set to east coast time. I've contacted a few people at OWL about this and it should be fixed soon if it's not already corrected. If it's not corrected and you happen to be doing your OWL assignment between 11:00pm and 11:59pm, please continue to do the assignment even if you get a "past due" message. When the clock is corrected, the system will automatically re-grade your assignment.

There's new OWL posted, due next Friday.

Lab hand-ins turned in by 3:00pm on Mondays get a bonus point, BUT next Monday is Labor Day, so the university will not be open (at least not completely). Therefore, for this assignment only you will get a bonus point as long as your assignment is in by noon Tuesday. The regular deadline, Wednesday at 3:00pm, is still in place.

Today in class we looked at ionic formulas again and checked out how to calculate percent composition from a chemical formula, and a chemical formula from percent composition. One question a few people had about the example I did was "Where did that 78g/mol number come from?" That's a number that would have to be given in the problem for you to use, it's not something you would calculate in that specific example.

If you have any input about the SI schedule, please let Sara know. If none of the current times fit in your schedule, or if some other time would work better in your schedule, she is open to adjusting the SI times to better serve as many student as possible. Keep in mind that Sara is a student, so she also has a lot of time commitments for classes and study time and other activities (and she probably likes to sleep an hour or two every night...).

Enjoy your 3-day weekend, be safe and I'll see you on Wednesday.
