3.25*10^25 atoms of neon gas equals how many moles of neon gas?

53.97 moles

Explanation:

First off, it is important to understand the following concepts;

Avogadro's number is a proportion that relates molar mass on an atomic scale to physical mass on a human scale.

Avogadro's number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to mol-1 and is expressed as the symbol NA.

Hence, the relationship between number of moles and number of atoms is given as;

1 mole = atoms

The question asks to find the number of moles atoms equals to.

so we have;

1 =

x =

upon cross multiplication, we are left with;

x = (1 * ) /

x = 53.97 moles
