I assume you mean 10.453x1023 atoms of sodium. 1 mole of anything contains 6.02x1023 representative particles (Avogadro's number), so if you divide the given number of atoms by Avogadro, you get 1.736 moles.
This is equivalent to 1,4 moles.
1 mole has 6.023 x 1023 atoms So, in 3.05 moles there are 18.37 x 1023 atoms
5,82 x 1023 atoms of tungsten equal 0,966 moles.
9,003 x 1023 atoms of iron correspond to 1,495 moles.

1 mole of lithium has 6.023 x 1023 atoms. So 5 moles will have 30.115 x 1023 atoms
1 mole of an element contains 6.022 X 1023 atomsso in 1.4324 moles no. of atoms is 8.659 X 1023 atoms
0,25 moles F2
0.94 moles.
6.02 X 1023 particles per mole X .75 moles = 4.52 X 1023 molecules.
Atomic mass: 207.2 grams.455 moles × (6.02 × 1023) = 2.74 × 1023 atoms of lead
5.66 X 1023 atoms of xenon (1 mole Xe/6.022 X 1023) = 0.940 moles of xenon ------------------------------
56 moles × (6.02 × 1023) = 3.37 × 1024 atoms
