Avogadro's constant is not an integer.Eebster the Great wrote:But Avogadro's constant is silly because it does not relate two units, just one: the mole. So instead of defining everything in terms of the second and physical constants, we define almost everything in terms of the second and constants and one thing as an integer.
With perfect instruments, we could take 12 grams of pure carbon and count the number of atoms, but we can't. We also can't count out 6.022000 X 10^23 atoms exactly.
Although we can easily conceive of both quantities with the same unit (but different scale), when we actually are measuring stuff we need to remember that we're making an inference when we try to go between macroscopic and atomic measurements.
