ik its the no. of particles in one mole...but it just seems like such a random no. to define as a quantity, if you get what i mean?
thats what it says in my notes but it seems VERY wrong..... :/
For instance one mole of carbon-12 is 12g and one atom of carbon-12 is 12 Daltons (atomic mass unit). 6.022x10^23 is just the number at which this happens. This is true for all chemical compounds. The number is just weird because it's a universal constant most of them are just wack the number system we use is completely abstract and made up. The universe doesn't care.
