Molecular orbital theory correctly predicts paramagnetism of oxygen gas, o2. this is because

Because the bond order in an oxygen gas is shown to be equal to 2, the idea furthermore supports the prediction of the molecular orbital theory in the paramagnetism of oxygen gas. This theory is primarily used when electrons are not included in the individual bonds for determining molecular structure.

Adozen is 1221/12 = 1.751.75 x 12 = 21therefore, 1.75 is the answer.

The answer is 4 i don't know if its right let me see.
