    6.0 g Al x (1 mol Al / 27.0g Al) x (1 mol Na / 1 mol Al) x (23.0g Na / 1 mol Na) = 5.1 g Na

    Since 1 mol = 6.022x10^23 atoms, then 1 mol Na and 1 mol Al have the same number of atoms.

    6g Al* (1 mol Al/ 26.98 g Al)= 0.22 mol Al

    If you have the same number of mold of Al and Na then you will also have the same number of atoms, because number of atoms is just mols times 6.022x10^23. Therefore for this problem you could say 0.22mol Al= 0.22 mol Na

    0.22 mol Na* (22.99 g Na/ 1 mol Na)= 5.11g Na
