CHM 110: Experiment 3B shared data (Section 2: Wednesday lab)

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 Wednesday lab section (section 2)!

Ratio of (mass product / mass BaCl2.2H2O):

  • 0.8495
  • 0.8519
  • 0.8520
  • 0.8510
  • 0.8503

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 calculator or a spreadsheet to find the standard deviation – you don’t have to calculate it by hand.
