In the sl system of units, the mole is one of
seven base units. it is frequently used in
chemical calculations. however, a mole of
something is just a particular quantity of it. it is
not a unit of measure in the way that meters,
seconds, and kilograms are. calculations
performed with the number of moles of a
substance could also be performed with the
number of particles of a substance. based on
this information, do you think that the mole
should be considered a base unit in the si
system? explain why or why not.
