Friday January 11th

Oops, sorry I haven't posted in a few days. Here is what we have done this week: Monday's Lab was about the temperature/volume relationship in gasses - and you tested Charles' law. Tuesday's and Thursday's lab was about designing an experiment with vinegar and baking soda to calculate the experimental value of R in the ideal gas law. Friday, today, we will be doing another lab on the ideal gas law. This time we are using a specific technique called the Dumas method to determine the molecular weight of an unknown volatile liquid. All week lab! Cool. Homework, thus far, has been the following things due: Tuesday: your lab calculations and a practice excercise out of the book. Thursday: design of your experiment in your lab book and finish reading chapter. Friday: questions 2-7 on the post-lab, and pre-read the Dumas method lab for today.
