Number of atoms equal the number of molecular orbitals as each atom has 1 atomic orbital and 1 electron.

Therefore,
Number of atoms = (mass/molar mass)*Avogadro's number = (7.90/22.99)*1.36*10^23 = 4.67*10^22 atoms.

Then,
Number of molecular orbitals = 4.67*10^22

How many molecular orbitals are present in the valence band of a sodium crystal with a mass of 7.90 g?
