How many atoms of neon (Ne) are in a 1452.96 moles sample of neon?

8749.73 * 10²³ atoms of He

Explanation:

Given dа ta:

Number of atoms of neon = ?

Number of moles of neon = 1452.96 mol

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms, ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 * 10²³ is called Avogadro number.

1 mole = 6.022 * 10²³ atoms

1452.96 mol * 6.022 * 10²³ atoms of He / 1 mol

8749.73 * 10²³ atoms of He
