we say that 1 mole is equal to 6.02 x 10 ^23 particles which consist compounds but what about just elements for example one mole Fe atom should consist 6.02x10^23 particles but which particles what are they for atoms?particle is gen

##1*mol## specifies ##6.022xx10^23## particles of any description.

If I have ##"Avogadro's number"## of ##H_2## molecules, I have ##2xx"Avogadro's number"## of hydrogen atoms; if I have ##"Avogadro's number"## of pairs of boots, I have enough boots to shoe ##"Avogadro's number"## of people (I'll probably have the wrong sizes tho). If you specify ##"Avogadro's number"##, you specify a given numerical quantity.

To continue, if I have ##"Avogadro's number"## of ##CH_4## molecules, then how many atoms do I have? And what is the mass of these atoms?
