Question: how many atoms are in 1 mole of aluminum?
Answer: Next, you must convert the mass of the sample to moles by using the molar mass of aluminium, which is equal to 26.982 g mol−1 . Finally, to convert the number of moles to atoms, use the fact that 1 mole of aluminium must contain 6.022⋅1023 atoms of aluminium → this is known as Avogadro's constant.
