1 mol of He contains apx 6.02214x10^23 atoms
It takes three helium atoms to create one carbon atom through nuclear fusion in stars.
To find the number of helium atoms in 542 kg of helium, you need to first calculate the number of moles of helium in 542 kg using the molar mass of helium, which is 4 grams/mol. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of helium to atoms.
Helium is a monatomic gas. That is its atoms do NOT combine with anything. It is the most unreactive of all elements.
No, 1 mole of hydrogen atoms does not equal 1 mole of helium atoms. One mole of any element contains Avogadro's number of atoms (6.022 x 10^23), so 1 mole of hydrogen atoms would have that many hydrogen atoms, while 1 mole of helium atoms would have that many helium atoms.
10g of helium has fewer atoms. This is because the atomic mass of helium is much higher than that of hydrogen, so the same mass of helium contains fewer atoms than the same mass of hydrogen.

The number of helium atoms is 6,022 140 857.10e26.
It takes three helium atoms to create one carbon atom through nuclear fusion in stars.
Hydrogen and helium make about 98% of the atoms in the solar system !
Helium does not form molecules but exists as individual atoms.
Helium has one kind of atom: helium.
A molecule of helium is composed of two helium atoms.
The answer is 800,424.1026 atoms.
To calculate the number of helium atoms needed to make a chain 1 cm long, divide the length of the chain (1 cm = 10,000 pm) by the diameter of a single helium atom (100 pm). So, 10,000 pm / 100 pm = 100 helium atoms. Therefore, 100 helium atoms placed end to end would make a chain 1 cm long.
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.
Mass of 1 Helium atom is 4 amu and mass of 1 Carbon atom is 12 amu. So there are 10 helium atoms and 10 carbon atoms
