Atoms in a mole = 6.02x1012 This is called the avogadro constant.
But this is quite complicated so we use carbon 12 as our example instead. Everything is related to carbon 12.
Moles = relative Atomic Mass.
Therefore, 1 mole of C is 12.
1 mole is O is 16.
1 mole of NaCl is 58.
2 moles of NaCl would be 58 x 2 = 116. In an equation it would look like 2NaCl.
1 mole of O2 is 32.
You know that there are 12 items in a dozen. No matter what the item, a dozen is equal to 12. A gross is another unit of grouping. There are 144 items in a gross. A score, another set group, is equal to 20 items. You can have a score of years or a score of rocks, but it will always be 20 items. Now, a mole is a unit of grouping, just like these examples. The only difference is that a mole represents a large number of items, 602 000 000 000 000 000 000 000 (or 6.02 x 1023) items to be more specific. What the items are doesn't matter. You can have a mole of molecules, a mole of ions, or a mole of stars. The number of items in a mole will always be 6.02 x 1023 . This number is known as Avogadro's number.
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".
The name given to the number of particles in a mole is Avagadro's number/constant
The total number of molecules is equal.
1 mole of silver contains Avogadro's number of silver atoms, while 1 mole of gold contains Avogadro's number of gold atoms. The molar mass of silver and gold can be used to determine the mass of each element in 1 mole. Both contain the same number of atoms per mole due to Avogadro's number.
True. One mole is 6.02x10^23 atoms/items.

6.02 x 1023I think it should rather be: A dozen is to twelve as a mole is to 6.02 x 1023.
No number since mole is an animal.
Avogadro's number is the number of "elementary entities" (usually atoms or molecules) in one mole. It is 6.0221415 × 1023
A mole of anything has the same number of molecules as a mole of anything else. The why comes from the fact that this is the standard definition as agreed by scientists. We have to have standards for things to work. A mole of anything contains an Avagadro number of particles. That number is 6.022 x 1023
A mole is equal to 6.022 x 1023. This number is called Avagadros number. A mole is generally abreiviated as "n".
A mole represents a set number of molecules, not just 1 molecule. There are avagadro's number of molecules in a mole. Avagadro's number: 6.022x10^23
Avogadro's number is the number of atoms or molecules of a substance that are present in one mole of that substance. It is relevant to the mole by its very definition!
It is the number of particles in a mole of any substance
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".
