  • I encourage you to select a Class Presentation compound (due by Friday, January 23 at 9 AM)
  • Start studying the material in Chapter 8.

This is the week of gases and intermolecular forces. One cannot understand gases without knowing the value of the universal gas constant, R (which has a value of 0.082057 L atm mol-1 K-1, or with different units, 8.3145 J mol-1 K-1 - memorize and use both values in all of your problems). Also, try to learn how PV = nRT (and its related PM = dRT) function. Please contact me if you have any questions, ok?

Here's what is happening in week 3 of CH 222:

  • Explore the material in Chapter 8. There are several tools to help you learn the material.... they include:
