In order to convert you would need to multiply the number of moles by Avogadro's number (6.022 x 1023). And that would give you atoms (or molecules or ions).
representative particles = moles x 6.02 x 1023 representative particles divided by 1 mole
44 moles of atoms
3,00 moles of Li have 18,066422571.10e23 atoms.
0,17 moles of stronium is equal to 1,02376394569.10e23 atoms.
4,80 moles of Fe contain 28,9062761136.10e23 atoms.
25.0 moles Ca x 6.02x10^23 atoms/mole = 1.50x10^25 atoms
The formula for converting is: atoms ÷ Avogadro's constant = # moles (1.8 × 1023) ÷ (6.02 × 1023)= 0.299 moles Cu
There are only two reverse operations.

3.9 moles of atoms
1,638 moles contain 9,864266723766.10e23 atoms.
multiply the number of moles by Avogadroa number
Seems to me we need to convert grams to atoms. So lets use mole conversion. When you convert from grams to moles, you divide the gram amount by the molar mass(a.k.a. atomic mass). So go look at a periodic table of elements and you'll see that pottasium's atomic mass is about 39.1 amu. So: .551/39.1 = .0141 mol Now that you have moles, you convert to particles(atoms). When converting from moles to anything you multiply. When converting from moles to particles you multiply by Avogadro's number(6.022 x 10^23). So: 6.022 x 10^23 x .0141 = about 8.49 x 10^21 atoms.
3,00 moles of Li have 18,066422571.10e23 atoms.
This is equivalent to 1,4 moles.
1 mole of water is 18g. 36g of water is thereforeequivalent to 2 moles. 2 moles of water contains 4 moles of hydrogen and 2 moles of oxygen and so there are6 moles of atoms in 2 moles of water. 6 moles of atoms x (3.6x10^24) = 36.1x10^24 atoms
10,0 moles of bromine atoms contain 60,22140857.1023 atoms.Attention: valid for bromine atoms !.
There are 9.33 moles of carbon in 5.62 atoms of carbon.
