Answer:
Molarity = 0.21 M
Explanation:
Moles <em>solute </em>(mol) = Volume <em>solution</em> (L) x Molarity <em>solution </em>(M)
0.56 mol NaCl = 2.7 L x M
M = 0.2074074074
Answer:
In a semiconductor, the bonding molecular orbitals that contain electrons are referred to as the valence band, while the antibonding orbitals that are completely empty are referred to as the conduction band.
The conduction band occupies a higher energy level than the valence band. The band gap is what separates the two orbitals.
