Divide 1.8*10^20 (unit: number) particles by 6.02*10^23 (unit: number per mole), Avogadro's number) and you'll get
3.0*10^(-4) moles of those particles
(In your case particles are atoms, but this is also valid for ANY kind of particles)

Actually it's not 3 atoms. A mole is a unit of measurement and 1 mole contains 6.02 x 1023 atoms. So if you have 3 moles it's 3 x 6.02 x 1023 which equals 1.806 x 1024 atoms. Hope this helped!
1.8x10^20 / 6.022 x 10^23 = 2.99 x 10^(-4) = .000299 moles
Also rounded could be 3.0 x 10^-4.
2.888 X 10^23 atoms of silver (1 mole Ag/6.022 X 10^23)
= 0.4796 moles of silver
One mole is equal to 6.02214179×1023 atoms (of any element).

1 mole of silver contains 6.022 X 10^23 atoms 62 moles of silver contains 3.73 X 10^25 atoms of silver
5.42 X 10^24 atoms silver ( 1mole Ag/6.022 X 10^23) = 9.00 moles of silver
One mole of atoms is 6.02x1023 atoms, so 10 moles of any substance would contain 6.02x1024 atoms.
2.0^25 moles of silver nitrate is .0301 moles.
In 3 moles of CH4, there are 18.06 x 10^23 times Hydrogen atoms.
1 mole of silver contains 6.022 X 10^23 atoms 62 moles of silver contains 3.73 X 10^25 atoms of silver

Quite a few moles of silver if you mean, 4.59 X 10^25 atoms of silver. 4.59 X 10^25 atoms silver (1 mole Ag/6.022 X 10^23) = 76.2 moles of silver ----------------------------
There are 6.022*10^23 atoms per mole so: 1.1*10^22Ag atoms* 1mole/6.022*10^23atoms = 0.018Ag moles
5.42 X 10^24 atoms silver ( 1mole Ag/6.022 X 10^23) = 9.00 moles of silver
The answer is 6,31 moles Ag.
4.55 moles AgNO3 (1 mole Ag/1 mole NO3)(6.022 X 10^23/1 mole Ag) = 2.74 X 10^24 atoms of silver
One mole of atoms is 6.02x1023 atoms, so 10 moles of any substance would contain 6.02x1024 atoms.
2.36 moles x 6.022*10^23 atoms/mole. Moles cancel and you are left with 1.42*10^24 xenon atoms.
1.50 x 10 to the 23 atoms of fluorine is equal to 0,249 moles.
The answer is 3,587 moles.
2.0^25 moles of silver nitrate is .0301 moles.
