Answer: 0.16 moles
Explanation: According to Avogadro's law, 1 mole of every gas at STP occupies a volume of 22.4 Liters.
Given: Volume occupied = 3.55 L
From Avogadro's law,
22.4 L of corresponds to= 1 mole
3.55 L of correspond to=
The ground-state electronic configuration follows the order of orbitals as shown in the first picture. So, we can deduce that the electronic configuration given is in order. However, each orbital must have a maximum number of electrons to be filled before it can move on to the next orbital. Since the d orbital must hold 10 electrons, that means that it should have held 5 electrons more. The missing 5 electrons were excited to the next 5p orbital. <em>Thus, there are 5 excited electrons.</em>
