6.02 x 1023 atoms is an arbitrary number.
Avagodro could have simply said that a "mole" is 12 atoms, or 1x1023 atoms, and achieved a similar result.
When we say that a mole of a substance in a given reaction yields one mole of this atom and one-half mole of another we are essentially saying that for x amount of a starting chemical, we produce x amount of the first element, and 1/2 x amount of the second element.
The x amount that we use could be 1000 atoms, 10,000 atoms, or 1x10100 atoms. In any case, we will get x number of one, and 1/2 x of the other, regardless of what x is. A mole, or 6.02x1023 atoms (or molecules) is the arbitrary number that we typically use.
By contrast, acceleration due to gravity is NOT arbitrary. The mass of the earth determines that for objects near the surface of the earth, there will be an acceleration of 11.9 m/s2 regardless of what we choose to call it. So gravity is Intrinsic (forced by something else) where a mole is just a convenient (arbitrary) way to talk about a certain number of atoms (or molecules).

What is difference between kilogram and mole?
mole is the unit of gas. Kilogram is the unit of Solid Mole is related to Avegatro No 6.623*10^23
A mole is an SI base unit that describes the?
A mole is a unit that describes an amount of a substance that has 1 unit of Avogadro's number in it. Avogadro's number is 6.022 E23.
What is the unit for mole in calculations?
The mole is an SI unit. It is the SI unit for the amount of matter in a substance.In fact, it is an SI base unit, meaning it is defined by measurements in a laboratory and not in terms of other units.One mole of a substance is the number of entities or elementary particles in that substance equal to the number of atoms in exactly 12 g of the carbon-12 isotope.
What is the unit of mole fraction?
Mole fraction is dimensionless. It's the amount of moles of species "A" divided by the total amount of moles in the mixture. So "mole A / mole total" equals "dimensionless". To add clarity in the use of mole fractions, one could add as "unit" mole A / mole "mixture".
What is the SI unit for the amount of a substance that contains as many particles as there are atoms in exactly 12 grams of carbon -12?
mole
What is the unit of mole in cgs unit?
gram mole
What is difference between kilogram and mole?
mole is the unit of gas. Kilogram is the unit of Solid Mole is related to Avegatro No 6.623*10^23
Are molecules per mole a unit for avogadro's number?
No, the unit is "per mole". The number could be atoms or molecules but that is not part of the unit.
Which is description of a mole?
The mole is a unit of measurement for the amount of substance or chemical amount. It is one of the base units in the International System of Units, and has the unit symbol mole.
How many volumes are in a mole?
Mole is not a unit of volume. Mole deals with numbers like dozen.
What is a mole used in chemistry as?
Mole is a unit of concentration in SI; a mole is equal to the molecular mass of a compound.
What is an arb unit?
An arb. unit is an arbitrary unit. You see these in plots where the specific values are not of important, but the shape of the curve is.
What evidence in chemical reaction in mole?
Mole is the the unit for amount of substance in SI.
In what unit is matter reported?
Mole
What is the SI base unit used to measure the amount of substance?

What is the unit of avogadros number?
The unit is "per mole", or mol^-1.
A mole is an SI base unit that describes the?
A mole is a unit that describes an amount of a substance that has 1 unit of Avogadro's number in it. Avogadro's number is 6.022 E23.
