1 mol of He contains apx 6.02214x10^23 atoms
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.
There are 6 carbon atoms, 8 hydrogen atoms and 7 oxygen atoms in C6H8O7 (2-hydroxypropane-1,2,3-tricarboxylic acid, citric acid).
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.

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
The number of helium atoms is 6,022 140 857.10e26.

Carbon atoms can be bonded together.
In the process of nucleosynthesis in stars, three helium atoms (which fuse to form carbon) must come together to create one carbon atom. This fusion process involves a series of nuclear reactions and energy release.
Helium does not form molecules but exists as individual atoms.
1 mol of He contains apx 6.02214x10^23 atoms
Helium has one kind of atom: helium.

A molecule of helium is composed of two helium 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.
