So, in a mole of anything, there are 6.022x10^23 molecules or atoms. There are 1000 millimoles in a mole, so 6.022x10^23/1000 is 6.022x10^20 atoms.
How many moles are there in 9.0333x1024 atoms of helium
The answer is 800,424.1026 atoms.
helium has 2 electrons
3.7x10^3 millimoles is 3.7 moles. To convert moles to atoms, multiply by avagadro's number. 3.7 x 6.022x10^23 is 2.22814x10^24 atoms.
1 mole or 4 g or 0.004 kg of Helium has 6 x 1023 atoms. So, 431 kg of Helium have 65 x 1028 atoms
The number of helium atoms is 6,022 140 857.10e26.
Helium does not form molecules but exists as individual atoms.
Helium has one kind of atom: helium.
The answer is 8,1547.10e25.

1 mole of helium (or 4 g or 0.004 kg) has 6 x 1023 atoms. So, 590 kg of helium will have 8.9 x 1028 atoms
4 g (or 1 mole) of helium will have 6.023 x 1023 atoms
1 mole of helium (or 4 g or 0.004 kg) will have 6 x 1023 atoms. So, 544 kg will have 8.16 x 1028 atoms.
