What is the mass of 4 mole atom?

Now, the atomic mass of Aluminum is 27. So, the mass of 4 moles of aluminum atoms is 108grams.

How many atoms are in 4 moles?

Since 1 mole of silicon contains 6.023 x 10^23 atoms, 4 moles will contain: (4 moles) x (6.023 x 10^23 atoms) = 2.4092 x 10^24 atoms. Thus, 4 moles of the silicon element contains about 2.4 x 10^24 atoms. Hope this helps.

What is helium-4 made up of?

Helium-4 is made of 2 protons (the part of an atomic nucleus with a positive charge), 2 neutrons (the part of an atomic nucleus with no charge) and 2 electrons (the part of an atom that goes around the nucleus with a negative charge). Many helium-4 on Earth is produced from the alpha decay of heavy elements.
