Today we took our first set of notes over our new unit, chemical composition. This section shows how you can convert from representative particles to moles, moles to representative particles; moles to mass, mass to moles; volume at STP to moles, and moles to volume at STP. By using these conversions, the number of moles, atoms and grams in an element can be determined. I find the mole road map we were given in class to be very helpful in converting between the different properties. The mole road map seems like it will be very beneficial throughout this unit.

I also find the mole road map really helpful! It's nice to be able to see the conversions in a logical pattern.
ReplyDeleteYour post is very helpful about understanding conversions. I like your picture of the road map. I would like to see an example problem so the reader understands what the numbers mean.
