Physical Science 20 - Sept 24

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.
