" On the other hand, the number of atoms can be measured with only numbers, so a unit of measure is not needed"

Are you saying that you'd rather use 6.02214076 x 10^23 for every calculation? That just seems cumbersome especially when you're dealing with compounds (even more specifically acids)

Please show me how you'd convert 1M solution of H2SO4 to normality using your method.

Are you saying a mol should replace avagadro's number then?

distance cannot be measured with just one number, you cannot say that something measures 10 distances, so a unit of measurement is needed. On the other hand, the number of atoms can be measured with only numbers, so a unit of measure is not needed

" I think it should be a number (like pi) that equals the avogadro number."

that's like saying 1 meter should just be (1) and not 1m or 100cm or 0.001km.....it simply makes no sense.

Pi is a mathematical constant while a Mole is a unit of measure. Pie doesn't measure anything.

But that's already avagadros number, a mole is just a multiple of that which let's you normalise atomic mass in solution

I mean that in the SI the mole appears as a fundamental unit (such as the meter or the kilogram). I think it should be a number (like pi) that equals the avogadro number.

If you say you have one mole of atoms it means that you have 6,022 (10^23) atoms, so the mole could be a number and it would be the same

I don't understand this. The number or 'magnitude' is Avogadro's number and was selected to make a mole equal to the atomic mass of the substance in grams.

Are you saying a mole should be avagadros number and not a a multiple of the atomic mass in grams?

Are you talking about chemistry?

If moles weren't a unit, how would you do stoichiometry calculations?
