What is a mole?
A mole is simple unit of measurement. Grams are not the unit
of measurement you want when you have a chemical reaction when you are trying
to find the atoms and molecules, so we convert it to moles. Moles are based on
the particles found in carbon-12, which is 12.00 grams. That number is also
called Avogadro’s number which can be written as 6.02x10^23. But instead of
writing out that number, people just refer to it as a mole so they don’t have
to write out the long number. You might say that why can’t the unit just stay
at grams but that’s because moles have been an easier way to convert between
atoms and molecules. It may seem
difficult at first but the more you use them and get use to them it becomes
much easier to use. It may seem like it’s not a normal unit but you will find
that it is very important and useful later on in solving equations.
