Updated on: September 25th, 2023
The number of atoms in 52 u of He is 7.8286 x 1024. We know that one mole contains 6.022 x 1023 atoms.
Therefore, One mole of He = 4u
Hence according to the question, we can write as:
Number of moles in 52u of He = 52/4
= 13 moles
Number of atoms in 13 moles = 13 x 6.022 x 1023
= 7.8286 x 1024

Uses of Helium
- Most commonly, weather balloons and altitude research employ helium.
- It functions as an inert protective gas during autogenous welding.
- The only cooler that can lower temperatures down below 15K is this one (-434oF).
- Helium is used to create crystals of germanium and silicon.
- Since helium diffuses through solids much more quickly than air, it is employed in industry to locate pipeline breaches.
- This element is used in gas chromatography as a carrier gas.
- Due to its low melting point, liquid helium is used extensively in cryogenics, MRI, and superconducting magnets.
Summary:
Calculate the number of atoms in 52 u of He.
The number of atoms in 52 u of He is 7.8286 x 1024. Helium is the element that you can find on the upper right side of the periodic table with atomic number 2. It comes first among the family of noble gases.
