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:.

• I will give you back your reports for the experiments we’ve done up through Experiment 6 during next week’s lab.
• You won’t get back your report for Experiment 7 before the lab test, so make sure you take good botes on Experiment 7!
• The experiment will not cover the introductory experiment specifically, but the main concepts in the introductory experiment are covered in Experiment 2.

Here’s the sample calculation for experiment 3B that we discussed at the ned of today’s class.

[CHM 110: Sample calculation for Experiment 3B]

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):

• 0.85117
• 0.84988
• 0.85131
• 0.85040
• 0.85230
• 0.85094

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.
