Answer:
Moles of air 0.1245 mol.
Explanation:
Given data:
Pressure = 1 atm
Temperature = 293 K
Volume = 3 L
Number of moles = ?
Solution:
PV = nRT
R = general gas constant = 0.0821 dm³ atm . K⁻¹ . mol⁻¹
Now we will put the values in equation
PV = nRT
n = PV / RT
n = 1 atm . 3 L / 0.0821 dm³ atm . K⁻¹ . mol⁻¹ . 293 K
n = 3 / 24.1 dm³ atm. mol⁻¹
n = 0.1245 mol

Explanation:
Resonance is a valence bond terminology which is used to describe a situation in which a single structure is not able to fully describe the nature of bonding in a molecule.
In such cases, we invoke more than one structure. Each structure contributes significantly to our understanding of the nature of bonding in the molecule under consideration and these structures are called canonical or resonance structures.
The real structure of the molecule is somewhere in between these structures - a resonance hybrid.
For ozone, two equivalent structures can be used to describe the bonding in the molecule. These structures are equivalent as shown in the mage attached. We can see from these structures that the bond order in ozone is 1.5(one and half bonds)
