The number of helium atoms is 6,022 140 857.10e26.
Hydrogen and helium make about 98% of the atoms in the solar system !
Helium does not form molecules but exists as individual atoms.
100 million helium atoms, being the number (1.0E-2 m)/(100E-12 m).
Helium has one kind of atom: helium.
The answer is 8,1547.10e25.
How many moles are there in 9.0333x1024 atoms of helium
The answer is 800,424.1026 atoms.
helium has 2 electrons
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
