Final answer:
This question is related to the diffusion of oxygen molecules across the cornea, an application of Fick's laws of diffusion in the field of chemistry, but cannot be answered without additional data.
Step-by-step explanation:
The question pertains to the concept of diffusion in chemistry, which is the movement of molecules from an area of higher concentration to an area of lower concentration. Specifically, the question mentions the ability of oxygen molecules to cross the cornea at a temperature of 30°C. The referenced materials provide information on estimating Henry's law constant for oxygen in water at this temperature and discuss the solubility of oxygen. However, without additional context, such as the diffusion coefficient of oxygen in the corneal tear layer or a specific rate of oxygen transport, it is not possible to accurately answer how many oxygen molecules would cross the lens in 1 hour. To answer this sort of question, one would typically need to apply Fick's laws of diffusion, which can mathematically describe the flow of molecules in a medium.
