Physical Science - March 4

Today in class we began to look at how to convert information using the idea of the mole.  This involved using the molar mass to convert from the mass of a substance to moles of the substance and visa versa.  As well, we can use Avogadro's number to convert from the number of particles of a substance to the moles of the substance and visa versa.  We just did a couple of examples (slides 16 and 17 in the powerpoint called The Mole) outlining the process.  We will work through a couple of more examples tomorrow and then work on Assignments C18 and C19.
