Im debating with myself whether moles are truly a units because unlike other units moles are just a conveniently large amount but unlike other units moles could fully be replaced by a factor
Yeah they aren’t a unit in the sense that they make a non-quantifiable measure quantifiable. In dimensional analysis they would have the dimension [1]. But they can still be regarded as a unit since they act in the exact same way, just like other factors do. But yeah, they are more akin to the SI prefixes like kilo, or something like a dozen or a gross.
A mole isn’t just convenient. I’m sure there’s a youtube somewhere that explains it but advagadros number is a product of the fact that: 1) every atom of an element has a weight (or at least an average) and 2) atoms interact in integer quantities. If you put those two together there is a common multiplier for a stochiometric equation that is related to the mass of a given atom in that stoichiometry. That multiplier is the the mole.
edit: I guess that’s kind of a factor, but it’s really more of an derived unit. If there was a new element discovered a mole would still describe it’s stoichiometry, and IIRC that’s how a lot of the periodic table was filled out my Mendelov.
Atomic mass is measured in u, not atoms. That would be moles.
And measuring in moles is way less crazy than measuring in eagles.
Really? Now I have to go dig up some moles…
Which, ah, species is best here?
