I don't know what mole is and I read a lot of answers, is it like a dozen of atom, or is it like a unit, like meter?or is it something else?
Tonywryip said:What does that do, say a mole of hydrogen atoms, what is the purpose of the mole? What can a mole of hydrogen atom achieve? And does it have anything to do with atomic number of hydrogen?
Tonywryip said:What about Avogadro number's, is that the same as mole? And my dad said that mole connects the molecular world to our world(the bigger one), is that true, if it is, how is it true?
Tonywryip said:O, and how do you quote ?
Drakkith said:It's the constant that is defined as the number of atoms in a Mole of a substance. It has no actual connection between our world and the quantum world, just a mathematical one. It can be used as a scaling factor for certain things. See here for more: http://en.wikipedia.org/wiki/Avogadro_constant

corvuscrypto said:It doesn't do anything, it is just a representation of a scaling factor (you know this factor as Avogadro's constant). The reason we like using the mole in equations as opposed to just one particle is that it is simply easier. Easier for measurements and easier for calculations. Since it's early use, however, many relationships have been based off of this scaling factor including Boltzmann's constant and other various relationships. The number of particles per mole was originally based off of how many atoms were in 1 gram of hydrogen. It has since been redefined as the number of atoms in 12 grams of carbon.
The mole doesn't depend on atomic number or vice versa. Molecular weight on the other hand is related to the number of grams per mole.
I hope that helps.
