why is the mole considered a base SI unit?
don't tell me what they are, i already understand avogadro's number and all that shit. my problem with the unit is that it's dimensionless, it's just a number of something. a mole could easily be a mole of oranges, or a mole of elephants. it doesn't describe anything dimensionally like the other units (meter, kilogram, etc) do.
so why is it a unit, especially when we have the technology now to reliably measure atoms in accurate ways such as mass?

A mole is just a conceptually different way of measuring something entirely than physical dimensions. It has more in common with the concept of "a dozen" or "twenty of them" than with "a meter" or "a gram".
The fact that it's so different is exactly what makes it useful, though. It describes a different concept than volume or weight.

Figures. Fuck off, illiterate retard.

The utility of the mole is simply that it is a human-scale amount. A good spoonful of graphite powder would be about a mole of carbon. Only kink is they didn't make it a round power of ten, but oh well.

The mole is a convenient number in that it retains ratios of elements in molecules while at a macroscopic scale. It allows us to make predictions about molecular reactions on that scale using atomic properties of its constituent elements.

Many would agree with you but SI is shit so there you have it.

You are retarded.
Avogadro's number is defined to be the inverse of the atomic mass unit, so that the atomic weight equals the molar mass.
This makes one of them a measurable constant of nature and dependent on the definition of the other units.

It's a combination of the arbitrary fetishes of both carbon-12 and the gram.
Shit gets all fucked up when you realize hot objects weigh more than cold ones.
