Question

Calculate the number of atoms in 52 amu of He.

Answer 1

13 Atoms

Given:

Atomic mass unit of Helium

= 52 amu

To Find:

Number of Atoms in Helium

Molar mass of helium:

= 4 amu

Formula used to calculate the no of atoms:

= Given / Molar Mass

Substituting the values we have found into this formula we get:

= 52 amu / 4 amu

= 13 atoms

Therefore, the number of atoms present in 52 amu of Helium is 13 atoms.
