Aether is known to fill the Universe and to serve as
light conducting medium. Aether is ideal gas of elusive
aether atoms with speed of sound 300,000,000 m/s,
predicted by Mendeleev to occupy the zeroth cell in
Periodic table. Einstein's famous cosmoligical constant
accounted for omnipresent aether, the negative density
of aether ρA compensating for average observable
density of matter in the Universe ρU = -ρA = 10^-30 g/cm³.
Estimate universal pressure of aether.

"no mole weight or a temperature"
Well, maybe they cancel each other

I thought that the presence of aether was disproved by Einstein. Anyway, since we don't know its mole weight or you haven't given us a temperature, we really can't give a reliable estimate of something that probably doesn't exist.

It is identically zero throughout all space and time. The Michelson-Morley experiments showed that no such thing exists, and Einstein's special theory of relativity, now established science, does not allow for the existence of such a thing. The cosmological constant present in the general theory of relativity has nothing to do with aether.

OMG you guys have NO sense of humor.
You're supposed to put yourself in a nineteenth century frame of mind and just DO the problem, not ***** about how the twentieth century disproved the aether hypothesis.
Lemme think about it a bit.
So if you want a flat geometry,
8(pi)G(rho critical) / 3H^2 = 1
Solve that for rho critical. The density of the aether will be the difference between the rho critica and the observed density of matter.
If you assume that the hubble constant is, in fact, constant, then
pressure = (rho)c^2 / 3
(rho) = 3H^2 / 8(pi)G (solution of eq up above)
pressure = H^2 c^2 / 8(pi)G
H = Hubble constant = 77 (km/s)/Mpc

The aetherial hypothesis was disproved in 1887.

There is no such thing as the aether
