A mole present in 9.3 $\times$ $10^{24}$ atoms Na is 15.44 mol Na.

Explanation:

A mole of a substance or a mole of particles is defined as exactly 6.02214076×10²³ particles, which may be atoms, molecules, ions, or electrons.

One mole of any element contains 6.022 $\times$ $10^{23}$ atoms of that element.

In order to determine how many moles are in a given number of atoms, divide the given number of atoms by 6.022 $\times$ $10^{23}$ atoms / 1 mol .

= ( 9.3 $\times$ $10^{24}$ atoms Na $\times$ 1 mol Na) / 6.022 $\times 10^{23}$ atoms Na

= 15.44 mol Na.
