4.5665 * 10^-5 moles

Explanation:

Your working out doesn't seem to make sense. This is not a difficult problem, if you just calculate the number of protons, then convert the amount to moles.

There are 11 protons in a sodium atom, so the are 2.50 x 10^18 x 11 protons altogether: 2.75 x 10^19 protons.

Number of moles: (2.75 * 10^19)/( 6.022 * 10^23)

4.5665 * 10^-5 moles
