Answer:
we add only the the same highest enegy levels :3s&3p=2+4=6
The internal energy r<span>efers to the total energy of a system. The enrgies are kinetic energy and potential energy of the system that makes up the whole energies of the system.</span>
Just do 6 x 2.2
6 x 2.2 = 13.2
1. V= 161
2. V = 37.3

Charles's Law states that
<em>When the gas pressure is kept constant, the gas volume is proportional to the temperature </em>
