Interesting and very plausible. I assume its a liquid state at this percentage I don't know. The reason I ask is other sources such as NX Express and even good old Wikipedia have it at 33%. Not arguing I sincerely don't know this answer.
Edit:
The weight of the molecules will change according to temperature and state of molecules. (Gas vs Liquid)
