You answered one of my questions, i asked "if a mole is defined as the number of H atoms in 1 g of hydrogen, how many H atoms are there in a mole?" and you told me it was Avogadro's number 6.022 x 10 ^ 23... and thank you so much, but can you tell me why that is... is it because you multiplied 1 by avogadro's number? or for some other reason...
If it had been the same question, but with oxygen as the element, not hydrogen, would the answer still be the same? please help me!

Avagadro's number is a constant, and yes it applies to anything. 1 mole of hydrogen is 6.022 x 10^23 atoms and 1 mole of oxygen or any other element would be that exact same number of atoms

If you convert the AMU to grams, that is how many grams one mole (6.023 x 10 to the 23) atoms will weigh.
Or . . . Avogadro's number can be applied to any substance. It corresponds to the number of atoms or molecules needed to make up a mass equal to the substance's atomic in grams.
It is constant.
Get an "A".

For future reference, if you need to get in touch with someone who's already answered one of your questions, you can go back to your question and click on his picture where he answered you. That will take you to a page all about him, from which you may e-mail him without having to ask another question and hope he sees it.
