Physical Science 20 - Sept 28

Today, we did another example related to molar conversions.  We did an example where we found the mass of a certain number of atoms of the substance.  This example involved 2 steps, first converting our given information into moles and then converting from moles into the required.  Students then had a chance to work on Assignment C18. We will take this up tomorrow.  We will also do our first lab tomorrow on the mole.
