In the SI 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.

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
