Physical Science 20 - Oct 14

Today we spent most of the class going over Assignment C20.  We then started looking at solving problems that involved volumes of gases at STP (which means Standard Temperature and Pressure).  This involves using a conversion factor called the molar volume (22.4 L of gas/1 mol  of gas).  Students copied down a couple of examples and then the bell went.  We will solve these problems tomorrow and then work on Assignment C21.
