The answer is: One mole of ANY element contains the same number of atoms as one mole of any other element.
Since a mole of any element is equal to [tex]6.022x10^{23}[/tex] atoms (Avogadro's number) of that element, we can conclude that an element has the same number of atoms ([tex]6.022x10^{23}[/tex]) than any other element.
For example:
[tex]1molelOfO=6.022x10^{23} atomsOfO[/tex]
and
[tex]1moleOfH=6.022x10^{23} atomsOfH[/tex]
We can conclude that both compounds have the same amount of atoms ([tex]6.022x10^{23}atoms[/tex])
Have a nice day!
One mole of any element contains the same number of atoms as one mole of any other element.
Moles is define as the ration of the given mass of any substance to the molar mass of that substance.
In one mole of any substance, exact 6.022 × 10²³ number of atoms of that substance will present and this number is know as the Avogadro's number. For example, in 1 mole of O₂ molecule 6.022 × 10²³ number of oxygen molecules are present.
