How sure are we that the gasohol in service station tanks contain no water?
I would never bet on it.
Is it possible that all tanks containing gasohol contain at least some water
dissolved?
Extremely likely, from past experience (pumping gas decades ago)
Is it a certainty that the alcohol added to gasoline contains no dissolved
water?
No. Definitely NOT a certainty.
I don't know the answer to any of these questions. Does anyone know, for
CERTAIN, any of these questions?

My guess is that all service station tanks, (unless they have never had
straight gas, and that they are BRAND NEW) have had an opportunity to get
some water in their tanks. If that is the case, and you put gasohol in
them, the gasohol samples will contain some dissolved water, and the seltzer
test will work.

If that is the case, doing a scientific test with clean gas and adding water
free alcohol will prove nothing.
Except you can NEVER say NEVER, and ALWAYS avoid ALWAYS.
It is POSSIBLE you may GET totally dry gasohol. The probability that
it will remain dry is slim.(alcohol is hygroscopic - it attracts and
binds water)
