Explanation & Answer

Thank you for the opportunity to help you with your question!


 Take given mass and divide by Sodium's molecular mass

5.45g/(22.99g/mol) = .2370 moles

then multiply yours moles by Avogadro's Number

.2370 X 6.022*10^23 = 1.4270*10^23 atoms.

The number of atoms will be equal to the total number of atomic orbitals since each atom has 1 electron and atomic orbital. so,

number of atomic orbital in 5.45g of Na crystal= 1.4270*10^23
