Physical Science 20 - March 12

Today in class we went over Assignment C20.  We then learned how to convert from moles of a gas to liters of a gas at Standard Temperature and Pressure (or STP).  At STP, 1 mole of gas occupies 22.4 L of space.  We went through a couple of examples and then worked on Assignment C21.  I will check that tomorrow.  Most students finished it in class.  They then started working on Assignment C22, which is a review of everything we have learned so far with the mole. We will work on this more tomorrow.
