minus-squarePosadas [he/him, they/them]hexagonhexbear6·4 years ago Counterpoint You may be wondering how chemists came up with a number like 6.02 x 1023but there is a reason! Chemists defined a mole as the amount of atoms that are in exactly 12 grams of carbon-12, which is Avogadro’s number! link
minus-squareRationalRhetoric [he/him,none/use name]hexbear7·4 years agoFunny enough the mole has recently (may 2019) been redefined to mean however much of any substance contains N particles https://en.m.wikipedia.org/wiki/Avogadro_constant link
minus-squareTankieTanuki [he/him]hexbear4·edit-24 years agoYes, the mole is was defined according to carbon-12, but a mole still represents only a quantity. The meter is defined according to the speed of light and a quantity of time, but the meter measures neither time nor speed. link
