How many moles are in 9.07 x 10^23 atoms of sodium chloride?

1.5 moles of sodium chloride are present.

Explanation:

Given data:

Number of moles of sodium chloride = ?

Number of atoms of sodium chloride = 9.07×10²³

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

9.07×10²³ atoms  × 1 mol / 6.022 × 10²³ atoms

1.5 moles of sodium chloride are present.
