Final answer:
The question as presented cannot be simplified as it lacks coherence and contains typos, but an example of correcting a small part identifies that neither 'a' (number 12) nor 'b' (He) represent molecules.
Step-by-step explanation:
The given expression, which includes various symbols and numbers, does not form a coherent mathematical question that can be directly simplified. Many of the parts seem unrelated to each other, and there are typos and irrelevant parts mentioned. However, as per the reference information, one point of clarification can be made regarding formulas representing molecules. For example, 'a' is the number 12, which does not represent a molecule, while 'b' is Helium (He), which is an element and not a molecule either.
It is important in mathematics to ensure that questions are well-formed and context is given to provide a meaningful answer. Without more specific details or correct syntax, it is difficult to provide a thorough solution.
