Question

how many mole have in 9.03×1000000000000000000000000 atoms Na​

Answer 1

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.
