use the following formula to determine number of moles number of moles = mass given/molar mass (mass on periodic table) one mole = 6.02x10^23 particles (molecules or atoms depending on substance) hence whichever mass has the greatest number of moles has the more atoms
3.85 atoms Al (1 mole atoms Al/6.022 X 10^23) = 6.39 X 10^-24 moles aluminum ( though 3.85 atoms seems unlikely )
To convert from moles to atoms, you need to use Avogadro's number, which is 6.022 x 10^23 atoms/mol. Therefore, to convert from 4.25 moles of Al to atoms of Al, you would use an equivalence factor of 6.022 x 10^23 atoms/mol.

Aluminium because if you look at the molecular weight, Al is nearly 4 times smaller weight per atom.

There are a total of 19 atoms in one molecule of Al(NO3)3. This includes one aluminum atom, three nitrogen atoms, and nine oxygen atoms.
By definition, 1 mole of anything is 6.022 x 1023 particles of that thing. So, 1 mole of Al = 6.022 x 1023 atoms Al 7.5mol Al x (6.022 x 1023 atoms Al/1mol Al)=4.5165 x 1024 atoms Al
To convert from moles to atoms, you need to use Avogadro's number, which is 6.022 x 10^23 atoms/mol. Therefore, to convert from 4.25 moles of Al to atoms of Al, you would use an equivalence factor of 6.022 x 10^23 atoms/mol.
1 mole Al ( and everything else ) is 6.022 X 10^23 atoms,so.... 6 mole Al (6.022 X 10^23/1 mole Al) = 3.61 X 10^24 atoms aluminum
There are 9 atoms of oxygen in one formula unit of aluminum nitrate (Al(NO3)3).

Al(OH)₃, or aluminum hydroxide, consists of one aluminum atom (Al), three oxygen atoms (O), and three hydrogen atoms (H). Therefore, the total number of atoms in Al(OH)₃ is seven: 1 aluminum + 3 oxygen + 3 hydrogen = 7 atoms.
