Answer:
the same number of atoms
Explanation:
Mole is defined as amount of substance which contains a fixed number of atoms/molecules/ions/particles and the number is known as Avagadro's number.
One mole is equal to 6.023X10²³ particles of any substance.
For example:
one mole of carbon will have 6.023X10²³ atoms of carbon and one mole of gold will have 6.023X10²³ atoms of gold
Thus the number of atoms will be the same in a given number of moles of any pure element.
Now the mass or weight could not be equal as the mass or weight will depend upon the atomic mass of element.
for example one mole of carbon will weigh 12grams
and one mole of gold will weigh 197grams
