This post will support an introduction to the mole concept for Prelim Chemsitry.
What is a Mole?
A mole is a unit of measurement used for atoms. 1 mole is equal to 6.022*10^23 atoms. This video will introduce moles.
This video will take you through some examples of using moles in calculations.
How Can We Relate Moles to Molar Mass and the Mass of a Sample?
There is an equation that describes moles in relation to the mass of a substance and it’s molar mass, it is n=m/MM (the number of moles equals to mass of the sample divided by its molar mass). The molar mass is simply the mass of 1 mole for that particular sample. This video will take you through some simple molar calculations as part of the introduction to the mole concept.
