Final answer:
The reasonableness of the average charge calculated in part C depends on the context and deviation from the expected behavior.
Step-by-step explanation:
The value of average charge calculated in part C may or may not be reasonable given the pI calculated in part A, depending on the specific context of the problem. The pI, or isoelectric point, represents the pH at which a molecule carries no net electrical charge. If the average charge calculated in part C is close to zero, it would be reasonable to assume that the pI is also close to the average charge. However, if the average charge calculated in part C is significantly different from zero, it may indicate a deviation from the expected behavior and further analysis would be needed to determine the reason for this deviation.
