How many atoms of Na would be in 2.53 moles of Na

15.24× 10²³ atoms

Explanation:

Given data:

Number of atoms of sodium = ?

Number of moles = 2.53 mol

Solution:

The given problem will solve by using Avogadro number.

The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

2.53 mol × 6.022 × 10²³ atoms / 1mol

15.24× 10²³ atoms

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.
