The answer comes to be 2158.53. You cannot have the fraction of the atom. The approximate answer will be too low to calculate. It will be too low to understand as well. The question should be 2.11 * 10 raised to 23 atoms.
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.

5.66 X 1023 atoms of xenon (1 mole Xe/6.022 X 1023) = 0.940 moles of xenon ------------------------------
0.94 moles.
This is equivalent to 1,4 moles.
2.36 moles x 6.022*10^23 atoms/mole. Moles cancel and you are left with 1.42*10^24 xenon atoms.
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
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
