Bring your lab notebook and a calculator to the lab exam on Thursday! You will turn in your lab notebook along with your lab exam.
Here are today’s CHM 100 notes. These notes cover the mole, formula weight, and mass to mole / mole to mass conversions.
I’ve posted study guides for chapters 5 and 6. You can use the links below or go to the [CHM 110 study guide page] to get them.
Just a reminder. Classes will meet on Tuesday, March 10th.
Our original schedule had the 10th as a no-class day, but that was changed after our snow days earlier in the semester.
Here are the dates of upcoming chemistry tests
Remember, SPRING BREAK is 3/16/09 – 3/20/09 !

[According to the national weather service], there’s a good chance that we will have at least a little snow accumulation on Sunday night and Monday morning.
[Tech has announced] that the school will be on a delay on Monday, in anticipation of some snowfall Sunday night.
From Tech's web site at 7:00 PM Sunday night
For students, classes before 11:00 AM are canceled. Here’s what that means for Monday’s chemistry classes.
CHM 100: The 9:30 AM lecture is canceled. Unless Tech changes their mind and closes the school all day, the 2:30 PM lab will still meet as scheduled. Quiz #4 is due on Wednesday morning at 9:30 AM.
CHM 111: Since our class doesn’t affect our 12:30 PM class. So unless Tech decided to close the school all day, we will have our test on chapters 12 and 13 tomorrow as scheduled.

I’ve posted a study guide for the first lab exam. You can see the study guide by either following the links on the right side of this page or by [clicking this link]. We will have our first lab exam the week after we complete Experiment 7
A few notes:.
Here’s the sample calculation for experiment 3B that we discussed at the ned of today’s class.
Here’s the shared data from CHM 110 Experiment 3B. These are the ratios of mass product / mass barium chloride dihydrate that you need to complete the table on page 74 and answer the questions on pages 75 and 76. This is data for the Thursday lab section (section 1)!
Ratio of (mass product / mass BaCl2.2H2O):
The write-up for Experiment 3B is due at our next lab meeting. If you have any questions about either the calculations or the rest of the write-up, either come by my office or ask here in comments. We will discuss the calculations for this lab in Tuesday’s class.
I recommend that you use your TI-83 caclulator or your spreadsheet to find the standard deviation – you don’t have to calculate it by hand.
CHM 100 and CHM 111 students:
If you missed Wednesday’s test and would like to take a make-up test, please come by my office (room 5416-C) tomorrow (2/13/09) between 9:30 AM and 10:45 AM. You will need about an hour to complete the test.
If you missed the test and have not come to take a make-up by 10:45 AM, your final exam will substitute for this missed test and any other missed tests will be given a zero grade.
